InvalidMessageException - No valid sessions. [InvalidMessageException - Bad Mac!][0] about libsignal_protocol_dart

When the error occurs?

[magbdev]

A session between two users is already set up and messages are exchanged, and at some point this error occurs. It seems to be a random moment.

Try the test function. https://github.com/MixinNetwork/libsignal_protocol_dart/blob/master/test/session_cipher_test.dart#L170

I'm receiving the same error message, in my case, it happens when i try to establish a new session with the mobile phone as the first recipient (I'm having a mobile client and a web client)

Somehow, it is just working when the APP the is the one to establish the session at first

[ronpetit]

Actually, my problem is because the mobile starts a session and then the webapp doesn't answer inmediately, so after the webapp answer the mobile APP can be closed and when is restored it doesn't have the established session alive to be able to decrypt the message

[WiRight]

same here

any updates with this issue?

[Tougee]

Have the identities of the established session changed?

I got the same error
InvalidMessageException - No valid sessions. [InvalidMessageException - Bad Mac!, InvalidMessageException - Bad Mac!, InvalidMessageException - Bad Mac!, InvalidMessageException - Bad Mac!, InvalidMessageException - Bad Mac!, InvalidMessageException - Bad Mac!, InvalidMessageException - Bad Mac!][0]

First time installing the app it works fine and second time when I reopens the app the message got encrypted but not decrypted and giving this above error.
