impossible to delete a room

[Dryusdan]

Description

I want delete some rooms. But when I try to remove it, Matrix return a 500 HTTP code :

{
    "errcode": "M_UNKNOWN",
    "error": "Internal server error"
}

And synapse log this output :

2020-06-16 18:22:42,765 - synapse.http.server - 113 - ERROR - POST-22824- Failed handle request via 'ShutdownRoomRestServlet': <XForwardedForRequest at 0x7fcda5e1b710 method='POST' uri='/_synapse/admin/v1/shutdown_room/!myamaizingroom:matrix.drycat.fr' clientproto='HTTP/1.1' site=8008>

I use this command :

curl 'http://127.0.0.1:8008/_synapse/admin/v1/shutdown_room/!myamaizingroom:matrix.drycat.fr' -H "Authorization: Bearer ${ACCESS_TOKEN}" -X POST -d'{"new_room_user_id": "@abuse:matrix.drycat.fr", "message": "This room has been removed from the matrix.drycat.fr homeserver due to lot of ressource consuption. Please don t use bridge with other tool. See CGU www.drycat.fr/fr/chartes/cgu", "room_name": "Room unavailable"}'

Steps to reproduce

• Create a room
• Send curl command into a terminal.

I have use this tool : https://github.com/matrix-org/rust-synapse-compress-state I'm not sure there's any connection because I can't remove any room process by this but a newer room can't is shutdown too.

It looks to me like Synapse can't find the user you're providing under new_room_user_id, does that user exist?

[dklimpel]

Perhaps related to: #7613
I want implement some validations to this API.

[Dryusdan]

The user exist yes :)

[clokep]

I was able to reproduce this with the following configure:

• Enable user_consent and configure block_events_error.
• Create an admin user.
• Create a room.
• Attempt to close the room, but set the new_room_user_id to an unknown user.

Are you sure the @abuse:matrix.drycat.fr user exists?

[Dryusdan]

Ha heu...
Nope, it not exist. Last ban doesn't need a real user.
I create it !

[Dryusdan]

My bad, sorry :x

It's work better now.
Thank :)
