Unable to create a service account key for app release

[vrampello]

Hi everybody, before doing this post I gave a look around for some other posts about the topic, but I didn't manage to find anything similar. So basically as you can see from the title I need to generate a key for the release of an android app, and I have all the permission to do it, but when I try to enforce the policy iam.disableServiceAccountKeyCreation, I get the following error from the google api:

errorType: DATA_FETCHING_EXCEPTION

message: Permission 'orgpolicy.policies.create' denied on resource '//cloudresourcemanager.googleapis.com/projects/projectname-425010' (or it may not exist).

 Do you have any idea why it might happen?
