I am using ServiceStack with MVC4 and getting 500 error when request parameters are long. I am posting ProductIds seperated by commas to controller via AJAX. In controller I have following call to servicestack API to retrieve data.
ResponseDTO res = restClient.Get(new RequestDTO { ProductIDs = ids});
//ResponseDTO res = restClient.Get(new RequestDTO { ProductIDs = "1234,1235,1236"});
If i submit small parameters in above, it works fine with no error. But when parameter string is in range of 1800 characters, it simply fails on above line and gives 500 Internal Server Error:
NetworkError: 500 Internal Server Error - http://localhost/Products/GetProducts
Exception Details: ServiceStack.ServiceClient.Web.WebServiceException: Not Found
is there a limit on GET method for posting large parameter request? Why does it fail for large request when for small parameters it successfully calls API, retrieves data via SQL procedure and sends to view correctly. What can I look into to solve this? Thank you!
p.s. when i debug via VS2012, i see exception details I see Message:Not Found and StatusCode: 404.
As Scott mentioned above, we tried POST for all methods and it fixed issue. I knew GET had limit on browser URL length but didnt think it matters as we had ServiceStack framework and all of their examples were using GET. Thanks again Scott.

I'm using Swashbuckle for a web api app in .Net Core 3.1. I want response examples for various response codes. I can get all of them working except HTTP 500. These are the attributes on the a particular method:
[SwaggerRequestExample(typeof(GroupInfoRequest), typeof(GroupInfoRequestExample))]
[SwaggerResponseExample(Status200OK, typeof(GroupInfo200Example))]
[SwaggerResponseExample(Status400BadRequest, typeof(GroupInfo400Example))]
[SwaggerResponseExample(Status403Forbidden, typeof(GroupInfo403Example))]
[SwaggerResponseExample(Status404NotFound, typeof(GroupInfo404Example))]
[SwaggerResponseExample(Status500InternalServerError, typeof(GroupInfo500Example))]
[ProducesResponseType(Status200OK)]
[ProducesResponseType(Status400BadRequest)]
[ProducesResponseType(Status403Forbidden)]
[ProducesResponseType(Status404NotFound)]
[ProducesResponseType(Status500InternalServerError)]
I can get all of them to render except the GroupInfo500Example. The application only returns an HTTP 500 to indicate an internal exception that isn't caught by other exception handlers. It is intended to return a body that contains, among other things, a GUID that can be passed in to our support organization to help them look up the exception in the application logs. I can not get the example to render for any 5xx error. If I change it to another status code, it renders, so it's specifically the 5xx result that doesn't render. I've checked the openapi json produced and it's not produced as part of the generated JSON. Is there a filter in place that keeps 5xx response docs from showing response examples?
Finally figured it out. I was missing part of the 'ProducesResponseType' attribute. It needs to have the return type as well as the HTTP status code. This works:
[ProducesResponseType(typeof(ADServiceOperationMultipleResult<GroupActionRequestForUsers, UserQuery>), Status200OK)]
[ProducesResponseType(typeof(ADServiceOperationMultipleResult<GroupActionRequestForUsers, UserQuery>), Status400BadRequest)]
[ProducesResponseType(typeof(ADServiceOperationMultipleResult<GroupActionRequestForUsers, UserQuery>), Status403Forbidden)]
[ProducesResponseType(typeof(ADServiceOperationMultipleResult<GroupActionRequestForUsers, UserQuery>), Status404NotFound)]
[ProducesResponseType(typeof(ADServiceOperationMultipleResult<GroupActionRequestForUsers, UserQuery>), Status422UnprocessableEntity)]
[ProducesResponseType(typeof(ADServiceOperationMultipleResult<GroupActionRequestForUsers, UserQuery>), Status500InternalServerError)]
Oddly enough, some status codes were including the example without it, but now the examples appear consistently as long as I include the method return type in the attribute.
I'm trying to request the supported timezones in the IANA format for a user (in Java), and getting the following error:
Error code: RequestBroker--ParseUri
Error message: Syntax error at position 57 in 'TimeZoneStandard='microsoft.graph.timeZoneStandard'Iana'''.
GET https://graph.microsoft.com/v1.0/users/email#redacted.com/outlook/microsoft.graph.supportedTimeZones(TimeZoneStandard=microsoft.graph.timeZoneStandard'Iana')
SdkVersion : graph-java/v2.3.1
Authorization : [PII_REDACTED]
400 : Bad Request
[...]
Based on our test suit, the request was working fine 3 days ago, and started failing with that error yesterday. We haven't changed anything for a while on our implementation, so I'm a bit baffled. For the request I'm essentially doing the following:
final String url = requestBuilder.outlook()
.getRequestUrlWithAdditionalSegment("microsoft.graph.supportedTimeZones(TimeZoneStandard=microsoft.graph.timeZoneStandard'Iana')");
final OutlookUserSupportedTimeZonesCollectionRequestBuilder builder = new OutlookUserSupportedTimeZonesCollectionRequestBuilder(
url, requestBuilder.getClient(), null
);
IOutlookUserSupportedTimeZonesCollectionPage page = builder.buildRequest().get();
The reason I'm doing this instead of the standard:
final IOutlookUserSupportedTimeZonesCollectionPage page = requestBuilder.outlook()
.supportedTimeZones(TimeZoneStandard.IANA)
.buildRequest()
.get();
Is because this isn't working as expected, as described here: https://github.com/microsoftgraph/microsoft-graph-docs/issues/7594 (the issue is for C#, but happens in Java too).
What I notice is that the GET url looks fine, and works fine in the Graph Explorer using the /me endpoint instead of the /users endpoint. But the string in the error message looks modified:
'TimeZoneStandard='microsoft.graph.timeZoneStandard'Iana'''
If I'm not mistaken, the outer apostrophes are simply quoting done when printing the error message, but there are further apostrophes introduced after the = sign, which aren't present in the GET URI, which might be causing the syntax error. Still, I have no idea where those come from.
Any help or hint would be greatly appreciated!
I have modified the call something like this
https://graph.microsoft.com/v1.0/users/UPN/outlook/supportedTimeZones(TimeZoneStandard='Iana')
It worked for me.
If a POST request requires that i send four data elements in the body, like:
{
"name":abc,
"surname":xyz,
"contact_no":1234,
"address":random_value
}
What will happen if I miss out some of the elements, for example if I call the web service with elements like,
{
"name":abc,
"surname":xyz,
}
What error is the server likely to throw ? I am having this issue because I am making a API call and it's giving me a HTTP error 500, so I guess it's not an error on my part, but this is one doubt i wanted to clear. Thanks in advance.
Its depends on the service structure (if all fields are mandatory or not),
and HTTP error (500) returns to server error or (server or link) not found .
I've been working with the grails plugin: 'grails-rest-client-builder:2.0.1'
https://github.com/grails-plugins/grails-rest-client-builder/
I'm experiencing an odd issue when I POST some data to a web service, a 500 Exception, even though the POST indeed is working successfully.
Class
java.lang.NoClassDefFoundError
Message
org/springframework/util/StreamUtils
Around line 195 of PageFragmentCachingFilter.java
if (CollectionUtils.isEmpty(cacheOperations)) {
log.debug("No cacheable annotation found for {}:{} {}"
new Object[] { request.getMethod(), request.getRequestURI(), getContext() });
chain.doFilter(request, response);
return;
}
The response that is coming back from the web service should look like this:
{"id":"9999","key":"IX-2247","self":"https://jira.xxxx.com/rest/api/latest/issue/9999"}
Again, the web service is correctly getting the values that I pass into it, and I verified this by checking the application that I'm posting to and I do see what I expect. Not only that, but I also receive an email from the system that I am POSTing to, and the email contains the correct values from the Grails application.
Here's the POST that I'm using:
def rest = new grails.plugins.rest.client.RestBuilder()
def resp = rest.post("https://jira.xxxx.com/rest/api/latest/issue/"){
auth "Basic xxxx"
contentType "application/json"
json builder.toPrettyString()
}
My hypothesis is that perhaps the issue is that the rest-client-builder is having some kind of issue with the response that is being returned from the web service.
Has anyone encountered anything like this before, where the service is working, but Grails throws a 500 error, even on a successful POST?
Please let me know if I need to provide additional information.
Thanks in advance!
Thank you all for the replies. I ended up upgrading my Grails application to 2.3.5, from 2.2.3 and now the code (above) works perfectly. The 500 error disappeared completely.
I am working on a flex application which communicates with a Rails backened.
When i request for some data, It sends back xml feed.
In some cases, if given parameters are not valid, then rails return an error feed with status code = 422 as following
email is wrong
But I dont get this feed in FaultEvent of Flex, How could i read error feed?
Thanks
Are you getting the result in ResultEvent in such cases? I am not sure for what all HTTP error codes FaultEvent will get invoke(I know only it goes for 404 and 500). May be its still going to ResultEvent as a valid result!
You can use HTTPService instead of URLLoader.
Flex HTTP results will not include the actual underlying HTTP response codes. It just doesn't work. (TM)
