There's an isolated issue with invm_95b3441b-308a-4083-bd26-e3b57dc61cf3 on my account usr_6fa4abc5-9952-4a0a-97de-b3598fbf6a5c which prevents one specific invite message (message slot 6, "Let's party!") from being updated, due to the June 8, 2025 API instability/outage incident . (Full details are available in the support ticket: #591843) ## Expected behavior on message slot 6 update (success scenario) The invite message is updated, canBeUpdated is set to "false", updatedAt date is updated, remainingCooldownMinutes is set to 60, and the API responds 200 OK. In the VRChat client, the message "Updated message text" should appear, and the message is expected to be updated. ## Alternative expected behavior on message slot 6 update (failure scenario) The API should respond with a HTTP response code 500 Internal Server error or similar, or returns an error message in the body JSON response. I don't expect the API to respond 200 OK in this scenario. ## Actual behavior on message slot 6 update (failure scenario) The invite message is not updated, canBeUpdated remains "true", updatedAt date is not updated (remains at old value "2025-06-08T01:12:29.649Z"), remainingCoolDownMinutes stays at its previous value 0, and the API responds 200 OK. In the VRChat client, the message "Updated message text" appears, and the message in the UI resets to the previous message from 2025-06-08T01:12:29.649Z (the old message received from the API).
