release_ids_filter returns zero responses

Running the below request:

releaseid_split='1,2,3'

def approvers(self):

return self._release_client.get_approvals(project=_project,release_ids_filter=releaseid_split)

Where I am passing in the release ids the results are always null in the above method call on the requests class unless blank data is sent through.

Running this via a request you get data back data as I would expect:
requests.get(f'https://vsrm.dev.azure.com/{ORG}/'+_project+'/_apis/release/approvals?api-version=5.1&releaseIdsFilter='+releaseid_split, auth=('', TOKEN)).json()

The same response just via a different means returns data as expected with the correct release data.

Is there something I am missing?

Empieza en _release_client.get_approvals y compara su solicitud release_ids_filter con la llamada directa a requests.get que se muestra en el issue. Reproduce ambas llamadas con los IDs de release 1,2,3 y con una entrada vacía; después, verifica que el cliente devuelve los mismos datos de aprobación de release que la solicitud directa.
