Anything else that would be useful to know?

Same error with an internal token or an access_token issued from /_matrix/client/v3/user/@user:domain.tld/openid/request_token

Fixed using another worker. I don't understand why federation worker isn't able to resolve that

Note that currently handling this endpoint on a worker is not supported: https://element-hq.github.io/synapse/latest/workers.html#available-worker-applications.

We'd accept PRs to allow this though.
