Department not found

Error message

Department ${departmentData._id} not found

What it means

Error "Department ${departmentData._id} not found" thrown in RocketChat/Rocket.Chat.

Solutions

1. Verify the department id in the event payload refers to an existing livechat department that the department converter can resolve.
2. Ensure the department still exists (not removed earlier) before the IPostLivechatDepartmentDisabled/Removed listener runs.

Example fix

Validate the department before use: const department = await LivechatDepartment.findOneById(departmentData._id); if (!department) { throw new Error(`Department ${departmentData._id} not found`); }
