`/_matrix/client/v3/createRoom: M_UNKNOWN (HTTP 400): Invalid user_id` about server HOT 4 CLOSED

Hi @mrusme, thanks for opening this issue.

In the configuration I used the format that was documented for the admin matrixid, which is: @xyz:matrix.org.

Can I ask you to provide me with the configuration you used? For redaction, feel free to set a placeholder. Specifically:

• What homeserver are you using?
• Are you prepending a @ to your Matrix ID?

Does pushbits require the account to be discoverable?

What do you mean with that?

I've already logged in as the account specified in matrix.username and created a room with the account specified in admin.matrixid.

Pushbits will create the rooms itself. It should not be an issue to create your own rooms generally.

What homeserver are you using?

Matrix.org

Are you prepending a @ to your Matrix ID?

To mine? Yes. But also tried without the @ in front -- same result.
To the PushBits user? Nope.

What do you mean with that?

Matrix allows for accounts to be discoverable, either by phone number or mail. That's not the case for my user. I was wondering if that might be a reason.

Pushbits will create the rooms itself. It should not be an issue to create your own rooms generally.

Understood, thanks. I nevertheless removed the room again, but that didn't help either.

I tried out your config using my own credentials. I realized the servers' Matrix user must be specified without @, likely because the underlying library expects so. However, I'm not able to reproduce this issue. I do not think that discoverability of a user account should play a role here, but feel free to try with a discoverable account and see if it works.
