Hey folks,
Are you able to reproduce the same issue for 8.x versions?
Could you please confirm the agent is still getting uninstalled even with this error?

Hi @pierrehilbert

Thank you for looking into this issue.
Yes the issue is also reproducible on 8.16.1 agent.

• If the agent is unenrolled from the UI, and then uninstalled, we observe this Invalid api key error.

Yes, the agent gets uninstalled even with this error.

Please let us know if anything else is required from our end.
Thanks!!

Yes if agent was unenrolled from Fleet, agent's attempt at an uninstall notification will fail.

We should probably modify this error to indicate it isn't a problem if agent was already unenrolled, perhaps we need to special case the invalid api key error in this case. CC @michel-laterman

Thanks @amolnater-qasource for the additional information.
Glad to read this is not something new and to see that @michel-laterman is already having a PR that will make the error clearer.
