GitlabHttpError(400) when making changes to existing merge request #325
Description
I have obtained object of gitlab.v4.objects.ProjectMergeRequest and I am trying to do some changes in given merge request - for instance, I am trying to close it:
mr = gitlab.v4.objects.Project.mergerequests.list()[0]
mr.state_event = 'close'
mr.save()
But at save() I got following exception:
Traceback (most recent call last):

gitlab.exceptions.GitlabHttpError: 400: b'{"error":"labels is invalid"}'
This code worked flawlessly with version 1.0.0.
Since this problem is related to labels (and according to the change log there was some changes in those in the latest release), on given merge request, there is only one label present. I haven't tried this on merge request with multiple or none labels, because I discovered it in a production environment, by an accident.
