I use fetch in try catch in Android webview, when the url has network issue or sslerror, I try to show the detailed error message about the reason, but the error only show "TypeError: Failed to fetch". Where to get the detailed error message?
Example code:
try {
await fetch("https://xxx");
} catch(error) {
console.log(error);
}

I'm writing an iOS app and I want to list all the files in a Firebase Storage folder. If I understand correctly, the way to do this is to use the StorageReference.listAll() function, which takes a completion handler as its parameter. The problem is that in an error case - for example if the user is offline - this handler fires twice: the first time with an error, the second time without. Here's my code, simplified for the purposes of this question:
let storageReference = Storage.storage().reference().child(userID)
storageReference.listAll { (result, error) in
print("handler fires")
if let error = error {
print("error")
} else {
print("no error")
}
}
In the regular case, this outputs "handler fires", "no error" which is what one would expect. If the user is offline, however, it outputs "handler fires", "error", "handler fires", "no error", which seems strange. Does anyone know why the handler is firing twice in the error case, and why the second of these firings reports no error?
Here is the full error log:

I am trying to initiate peer to peer connection in webrtc. I am using signalr as signaling server. I am getting error in all the browser when adding ice candidate. Below is the error and line of code. Please let me know how can i fix this.
Error in Firefox:
InvalidStateError: No remoteDescription.
Error in Chrome:
DOMException: Failed to execute 'addIceCandidate' on
'RTCPeerConnection': Error processing ICE candidate
Code:
if (signal.ice) {
console.log(signal.ice);
peerConnections.addIceCandidate(new RTCIceCandidate(signal.ice)).catch(errorHandler.message);
}
You don't need to build a new ice candidate object. Just adding signal.ice as ice candidate is enough. Here is the example from the official webrtc guide
signalingChannel.addEventListener('message', async message => {
if (message.iceCandidate) {
try {
await peerConnection.addIceCandidate(message.iceCandidate);
} catch (e) {
console.error('Error adding received ice candidate', e);
}
}
});
I am using the following code to send email for the logged in user.
await _graphClient.Me.SendMail(email, true).Request().PostAsync();
Initially it was executing be no email was sent. After poking around I figured out that a permission was not set. Unfortunately the try..catch around it was not tripped. My questions is if there is a way of detecting that an error occurred with this call.
Regarding
Unfortunately the try..catch around it was not tripped.
PostAsync() method should throw a ServiceException on error.
For example, in case of missing permissions:
try
{
await graphClient.Users[userId].SendMail(message).Request().PostAsync();
}
catch (Microsoft.Graph.ServiceException e)
{
Console.WriteLine(e.Error);
}
the following error should be printed:
Code: ErrorAccessDenied
Message: Access is denied. Check credentials and try again.
Using the standard autocomplete code with a searchbar:
placesClient.autocompleteQuery(searchBar.textField.text!, bounds: nil, filter: filter, callback: {(results, error) -> Void in
if let error = error {
print("Autocomplete error \(error)")
return
}
if let results = results {
for result in results {
print("Result \(result.attributedFullText) with placeID \(result.placeID)")
self.predictions.append(result)
}
}
self.placesTableView.reloadData()
})
Has been working for months and tonight it started reporting this error:
Autocomplete error Error Domain=com.google.places.ErrorDomain Code=-2 "The Places API server returned a response that we couldn't understand.

Anyone else experiencing this?
Looks like the service is back up. I raised a ticket with Google.
They identified the issue and are resolving it. Mentioned it could take a few hours.

I'm trying to use Google places API to get autocomplete.
I've checked everything:
API keys are activated (disabled every restriction)
I'm calling GMSServices.provideAPIKey and GMSPlacesClient.provideAPIKey
Initializing the object placesClient = GMSPlacesClient.shared()
The call I'm making is:
let filter = GMSAutocompleteFilter()
filter.type = .establishment
placesClient?.autocompleteQuery(textField.text!, bounds: nil, filter: filter) { (predictionList, error) in
if let error = error {
print("Pick Place error: \(error.localizedDescription)")
return
}
if let list = predictionList{
self.resultList = list
}
}
The error I'm getting is:
Printing description of error: Error

Has anyone else seen this problem in Xcode 8 iOS 10? Thanks
EDIT: Now it seems that some requests are working... Maybe the server is having problems?
