Could you try upgrading to version 2.0.1 of the library and let us know if this resolves the issue? https://github.com/pusher/pusher-channels-flutter/releases/tag/v2.0.1

I'm having the same issue even with 2.0.1 :/ Any ideas?

[benw-pusher]

Could you share more details about the changes you have made, perhaps sharing your code for review?

[kristapus]

I'm not 100% sure if it ever worked, because no changes were made recently... In debug mode, it works fine(atleast the app don't crash), but all the "fun" happens in release mode. Are there any config or other details that you would like to know?

[benw-pusher]

It would be good to get a small replication app if possible, or the code that is being executed when your app encounters this error. We can then look at replication and troubleshooting.

facing same issue :(

[benw-pusher]

We haven't been able to replicate this one and a replication sample hasn't been provided so we will have to close this out. FI you need further support please contact us at https://support.pusher.com/hc/en-us/requests/new
