### Additional information

Using homeserver `matrixdotorg/synapse:v1.38.0` from docker.

Seems live the key is missing, could be a version of Matrix that the client is incompatible with? When I use the Element client it works normal and there are no open invites left. The Rooms that I listen above are 1:1 (personal) chat rooms.

I have noticed that since the synapse 1.38 other libs added robustness for missing fields: ananace/ruby-matrix-sdk@6bbe67c and at the source project there is a open issue on it: matrix-org/matrix-python-sdk#320

Today I migrated from the Matrix HA addon (for the server part) that I used since a couple of days (wasn't working properly with messages lost, plus the addon no longer being maintained/supported) to Synapse 1.38 on a VPS. I'm running into the same error when setting up the integration in HA. The server itself is working fine.

Since I also upgraded HA (Core) from core-2021.7.2 to .3 today, I rolled back to .2 but that doesn't make any difference.

In the Synapse logging I see no error:

2021-07-21 22:04:20,320 - synapse.rest.client.v1.login - 271 - INFO - POST-3153 - Got login request with identifier: None, medium: None, address: None, user: '@homeassistant:redacted>

@GoSpursGoNL it is not ha that isn't working but a client depend. See linked issue above.

@johansmitsnl I also guess it is in the setup part of home assistant only. I was on 21.7.2 and it still worked, I updated synaps to 1.38 and it still worked, but the upgrade to 7.3 restarted home assistant and it broke at that point

[johansmitsnl]

@gvansanden omce you go to 1.38 without a ha restart works fine. When you restart ha (any version) it breaks.

I have the same problem

[MatijaTerzic]

Same problem here

[johansmitsnl]

A fix is merged to the master branch of the client library. Now we need a update of the library to bump the HA depend.

This issue is a duplicate of #52959 so I'll close this one.
