Self-hosted: Unable to Upgrade Panther to v1.44 due to InvalidInputException


As a self-hosted or CPaaS customer, your upgrade to Panther v1.44 fails, with the error message:

InvalidInputException: Caller is an end user and not allowed to mutate system tags.


To resolve this issue:

  1. Log into your AWS Console and open CodeBuild.
  2. Locate and delete the project called panther-pip-layer-builder. (This will not cause any outage; the project will be recreated upon your next deployment.)
  3. Retry the panther-pulumi CodeBuild job.


This issue occurs due to some changes AWS made to how resources are tagged. By removing panther-pip-layer-builder, the next deployment must rebuild it, using the latest AWS tagging rules.
