WARNING: Error, continue deployment: 201

[arrerezai]

Updating from early v10 to v10.3.3, I am experiencing some odd behavior when assigning new roles (although stating 201, which in itself is fine).

Below is a picture from the Deploy Role Assignments step where all new roles have this message in yellow presented:

When I look it up in the PS script disposed by Epac, the Set-AzRoleAssignmentRestMethod.ps1 has a section called "Process response". Looks to me that this section is being called although status code 201 should not be processed at all by that if-statement that says it only cares about status codes <200 or >=300.

Any thoughts why this is being shown?
