Error when logining in

[juliettebee]

Happy Holidays! I'm trying to connect imessages to my Matrix homeserver but whenever I login and send the authentication code I get this error in the logs: "ERR Panic in Matrix command handler error="invalid memory address or nil pointer dereference". Is there anything I can do?

@juliettebee I was running into this issue also. I was able to resolve it by modifying the nac_validation_data_url: value in the bridge's config.yaml file.

The placeholder value is "http://example.com/validation_data", and I initially left the "/validation_data" path in the value. Setting this value to the url for my relay server, without a trailing / or anything else, got it working. Hope this helps you or others that may have this same problem.

I'm getting this error too and also set the nac_validation_data_url to the URL without any trailing slashes and nac_validation_is_relay to true and nac_validation_data_token to the same value as the REGISTRATION_RELAY_SECRET environment variable but I'm also getting the same nil pointer dereference with the following stack trace:

I'm also a bit confused on when we are even supposed to give the registration code that consists of four alphanumeric words of 4 characters.

[tulir]

The token is the registration code, not related to the relay secret

Ah, thanks a lot for clarifying that!

Logging in seems to be successful now 🎉, although messages aren't being bridged.

Ah, I got it now. I forgot to disable iMessage on the iPhone. After doing that, I was able to log in after 2 attempts and messages are actually being bridged!
