Thanks @devlb for reporting this. Is it reproducible each time or, at least, sometimes?

[devlb]

Yes, this issue occurs every time — when the authUrl returns a 404.

final clientOptions = ably.ClientOptions( clientId: 'xxxx', authUrl: '404 url', );

Couldn't you please post a server response here? I assume that's a JSON with an error field.

[devlb]

decodedError is the string "Bad Request". I hope it can be handled compatibly without crashing.

Thanks for your response. It's now fixed here https://github.com/ably/ably-cocoa/pull/2136

[devlb]

I’m using ably-flutter v1.2.40, but the fix you mentioned is in ably-cocoa. So, which version of ably-flutter should I upgrade to? Or do I need to manually change the ably version in the Podfile?

[maratal]

It's not yet released in ably-cocoa, once it's released, we'll update flutter and let you know ASAP.

[devlb]

Please support it quickly — this is important.
