HTTP status 415 when calling "replicas/{id}/change_role"

[techguydave]

I'm trying to recreate the "Change Role" menu option in the replication GUI in a script, either through an SDK function or manually. From what I can tell, the switch_role() function doesn't work for async (as the documentation states). So I tried to call the API through the SDK at api/rest/replicas/{id}/change_role, but that returns a 415. I can confirm that I receive the same result in Postman.

I don't claim to be a Python guru, so let me know if I'm doing something wrong in my script.

Script:

from infinisdk import InfiniBox

system = InfiniBox("hostname", auth=("user", "password"))
system.login()

replica_id = system.replicas.get(remote_entity_name = "content_library").get_id()

change_role = system.api.post('replicas/' + str(replica_id) + '/change_role')
change_role.get_result()

Response:

Traceback (most recent call last):
  File "main.py", line 13, in <module>
    change_role = system.api.post('replicas/' + str(test_replica.get_id()) + '/change_role')

I should have searched the repo for examples/tests before filing the issue! It looks like changing

change_role = system.api.post('replicas/' + str(replica_id) + '/change_role')

to

change_role = system.api.post('replicas/' + str(replica_id) + '/change_role', data={})

solved it! This was omitted from the InfiniSDK documentation and might be a helpful addition on the Getting Started page.

@synth3tk replica objects have a change_role() method. Due to a mistake on our part it does not appear in the API documentation page (will be fixed in the next release).

This means you just have to write replica.change_role() and everything works.

@vmalloc Thank you very much, that worked!
