Failing to expand extensions on only one account - microsoft-graph-api

Question

Trying to run just a basic https://graph.microsoft.com/v1.0/me?$expand=extensions
But either get this error
Expected ',' instead of '{'
with
{"#odata.context":"https://graph.microsoft.com/v1.0/$metadata#users/$entity"{
"error": {
"code": "BadRequest",
"message": "The entity instance value of type 'microsoft.graph.user' doesn't have a value for property 'id'. To compute an entity's metadata, its key and concurrency-token property values must be provided.",
"innerError": {
"request-id": "39759fbe-06ed-4176-8cc3-efe167a532cb",
"date": "2017-05-17T22:47:35"
}
}
}
I am trying to find the id of my openExtensions my account so I can delete some to make room because I must of accidentally added too many but I can't even get a list of the extensions and I can't even filter it by id. All works fine with other accounts I think i must have just bricked my account while playing around with it. Any ideas?
EDIT
Trying the query https://graph.microsoft.com/v1.0/me?$select=id,displayName&$expand=extensions
results in
{"#odata.context":"https://graph.microsoft.com/v1.0/$metadata#users(id,displayName,extensions)/$entity","id":"MY ID","displayName":"MY NAME","extensions#odata.context":"https://graph.microsoft.com/v1.0/$metadata#users('MY ID')/extensions","extensions":[{"#odata.type":"#microsoft.graph.openTypeExtension"{
"error": {
"code": "InternalServerError",
"message": "Unsupported extension property type.",
"innerError": {
"request-id": "9fe3c7aa-f3d8-48be-90e4-b440516f9010",

}
}
}

I think I just ran into a similar problem.
I created my extension like this
var ext = new OpenTypeExtension();
ext.ExtensionName = "[Unique Name]";
ext.AdditionalData = new Dictionary<string, object>();
ext.AdditionalData.Add("[settingName]", "[settingValue]");
await graph.Me.Extensions.Request().AddAsync(ext);
But now I can no longer expand the extensions property for my account.
var profile = await graph.Me
.Request()
.Expand("extensions")
.GetAsync();
This throws a Microsoft.Graph.ServiceException:
Code: generalException
Message: Unexpected exception returned from the service.
When I try to make the request in the graph explorer, I get the following response,
{
"#odata.context":"https://graph.microsoft.com/v1.0/$metadata#users/$entity"
{
"error": {
"code": "BadRequest",
"message": "The entity instance value of type 'microsoft.graph.user' doesn't have a value for property 'id'. To compute an entity's metadata, its key and concurrency-token property values must be provided.",
"innerError": {
"request-id": "5e3887db-1687-461a-8d5c-da0f34eea83b",
"date": "2018-06-01T01:41:12"
}
}
}
}

So one of our devs took a look at the data and it looks like you were calling the API incorrectly - which was valid JSON, but not what our service can handle - especially on read back.
It looks like when you were creating an open extension, you were pushing the following in the payload:
{ "openTypeExtension": {
"#odata.type": "#Microsoft.Graph.Extensibility.openTypeExtension",
"extensionName": "roaming.settings",
"randvalue": 1
} }
But the openTypeExtension bit is not required and throws us off on a read back. What you should be sending is:
{
"#odata.type": "#Microsoft.Graph.Extensibility.openTypeExtension",
"extensionName": "roaming.settings",
"randvalue": 1
}
We've implemented a fix to prevent this in the future, which will roll out next week.
We have the IDs for your extensions, so you could delete them, but we're not sure how to communicate these to you securely. If you are OK with us providing them on this thread, please let us know.
Hope this helps,

I got the same error. I use Graph API lib.
Finally I was able to retrieve the extension other way - using Users.Extensions property (I guess it can be done against current user analogically - Me.Extensions).
I added the extension this way:
var additionalData = new Dictionary<string, object> { { "DataName", value } };
await graph.Users["userId"]
.Extensions
.Request()
.AddAsync(new OpenTypeExtension { ExtensionName = "uniqueExtensionName", AdditionalData = additionalData });
..and retrieving:
var extensionObject = ( await graph.Users["userId"].Extensions.Request().GetAsync() )
.CurrentPage[0];
