When creating a custom role definition with azure next gen, I got the following error

azure-nextgen:authorization/v20150701:RoleDefinition (roleDefinition):
    error: autorest/azure: Service returned an error. Status=405 Code="" Message="The requested resource does not support http method 'PUT'."

Is there an issue with the provider?

I think something is wrong with your value for

scope

yes, but this really lack of documentation from microsoft about what value is correct

name is a guid and scope is usually a resource id

okay, I got it 👍 roleDefinitionId should be a simple uuid like

roleDefinitionId: uuid.result

. I was trying to have a complex value like

/subscription/…

. It will be a challenge for pulumi to complete the doc, because azure doc or error message are sometimes very poor
