Updating the state of a merge request doesn't work

[Tzrlk]

Running gitlab updateMergeRequest --state_event close :projectId :mergeRequestId should close the merge request, and a subsequent call to gitlab showMergeRequest :projectId :mergeRequestId should reflect that change.

Unfortunately, when running that, absolutely nothing happens, and the subsequent query shows that no changes have been made.

I test it , it is success. Use this cmd to get right project_id

gitlab projects --filter 'item.path == "P2RKAndroid"'
369

Use this cmd to get right merge_request_id

 gitlab mergeRequests 369 --filter 'item.state == "opened" '
4655

Use this cmd to close merge request

gitlab updateMergeRequest --state_event close 369 4655

Use this to check state, I see it be closed

gitlab showMergeRequest 369 4655
