Error in DecryptCiphertext in session cipher class

[kanthanandam]

Good evening,

We are trying to use Signal with OMEMO in an XMPP application, however we are stuck in decrypting the message payload in session cipher:
NSData *decryptedKeyData = [sessionCipher decryptCiphertext:ciphertext error:&error];

Session builder processing pre key message returns "Invalid ProtoBuf" error -

And i am getting the error as mentioned below:

Could you please help us?

Thanks in advance

I'm facing the same problem. Is there any solution?
