Firebase SDK crashing when trying to play a show

[joshgare]

We're trying to play a show in our app with the following code

let player = BambuserPlayerViewController(showId: "JVRtMWhgaIpb47qJKfkO") { playerEvent in
    self.handleBambuserPlayerEvent(playerEvent: playerEvent)
}
present(player, animated: true)

The player presents with a loading indicator but the app then subsequently crashes with the following error.

*** Terminating app due to uncaught exception 'FIRInvalidArgumentException', reason: 'Document path cannot be empty.'

Unfortunately this means the SDK is unusable.

Hi @joshgare, Can you provide me with version of BambuserPlayerSDK you're using? Also are you facing this issue with all showIds? Please let me know while we look into this issue. Thanks

[joshgare]

@saeidbasirnia we've tried 1.2.2 and 1.3.0 and the crash occurs on both. We've tried 2 show ids and both caused the same crash.

[saeidbasirnia]

Thanks for the information. We'll look into this issue and I'll update this thread when we have more information.

[saeidbasirnia]

Hi @joshgare, We reviewed the issue and believe the issue is with the environment for the show. Default environment is global when not specified in the initializer, so you have to pass you're environment in init.

// If you're show is in an organization in EU
BambuserPlayerViewController(showId: "JVRtMWhgaIpb47qJKfkO", environment: .eu) 

You can check this out in our demo app. Please let me know if this resolved your issue!

Also a bug report is submitted for fixing the crash.

[joshgare]

Apologies, I didn't realise I had to specify environment. This is now working when the correct environment is used.

[saeidbasirnia]

That's great! thanks for the update. I'll close this issue now.

@saeidbasirnia might be worth keeping open until crash is dealt with? Could have an error log instead of crashing the whole app?
