Fatal error: Unexpectedly found nil #24

Closed bad-hambo closed 3 years ago

bad-hambo commented 3 years ago

Hi:

I am building the sample app and have gone through all instructions provided in the github. I am getting to the login page but it seems I encounter the error below; I've done this with a pre-populated user in my user group in addition to a confirmed new user through the app. It crashes when I use the tap the Sign In button. Please advise; I am hoping to leverage kinesis to stream video iOS devices. 

Fatal error: Unexpectedly found nil while unwrapping an Optional value: file AWSMobileClient/AWSMobileClientExtensions.swift, line 226

Piece of code where it fails:

Hi,

Can you tell us the device and iOS version you're testing the sample on?

bad-hambo commented 3 years ago

Hi:

iPad Pro 12.9" running on iOS 13.5.1

MushMal commented 3 years ago

@bad-hambo would you please upload the full logs and the stack info. @dswamina can you take a look at this once the logs are uploaded?

Seems like a crash in AWS mobile client and not the demo app.

Can you check this out: https://github.com/awslabs/amazon-kinesis-video-streams-webrtc-sdk-ios/issues/4

MushMal commented 3 years ago

Update please?

bad-hambo commented 3 years ago

@MushMal hey, checking out the suggestion.

@MushMal hi, I've resolved the issue with nil error; now I'm facing a different issue with Login Error:

There was an error with your login: The operation couldn't be completed. (AWSMobileClient.AWSMobileClientError error 13.)

Update:

Further googling and resolved issues; seems to be a bug in the AWSMobileClient SDK. Had to generate an additional user through the sign up UI to have it working. Cheers.
