{"access_token":"............................","token_type":"Bearer","matrix_server_name":"talk.domain.ltd","expires_in":3600}

But i get responce with error 500 and the following text

{
"error code": "M_UNKNOWN",
"error": "Matrix home server did not include "sub" in its response"
}

in the logs at the same time, I see

What is missing in the request? what is a "sub"? aditional info, configs needed?

reivilibre commented 4 months ago

I think sub is supposed to come from the /_matrix/federation/v1/openid/userinfo endpoint.

See: https://github.com/matrix-org/sydent/blob/fdde810deb6e8cf2bf74a3ac8a941564af3798bc/sydent/http/servlets/registerservlet.py#L98

Is the 'openid' endpoint enabled on your homeserver?

There doesn't seem to be enough information here in order to reproduce or fix this issue right now.

I will close this issue but it can be reopened (or a new issue, linking to this one, opened) if the issue recurs with more information available.

Thank you.
