Shared workflow is unable to be called from a personal/user repository

[jmcconathy]

In a GitHub Enterprise server (3.12.2), we have shared workflows stored in one organization. We have been using these shared workflows from other organizations in our enterprise without issue. Yesterday I tried using one of the shared workflows from within a personal repository, that is, a repository within my user profile on the GitHub Enterprise Server.

When I made an action that called the shared workflow, I got the following error:
Invalid workflow file. The workflow is not valid ... Error calling workflow 'myworkflow'. The nested job 'myjob' is requesting 'id-token: write', but is only allowed 'id-token: none'.

I tried a number of things with the settings on my repository but none eliminated this error, so I explicitly set permissions for the workflow token to be all write.

That eliminated that error, but then I get this one:
Called workflows cannot be queued onto self-hosted runners across organizations/enterprises. Failed to queue this job.

I have tried changing my repo settings to make it as permissive as possible, but nothing gets past this error.

What else could be blocking my personal repo from accessing a shared workflow?

The workflow repos are set to Public, and work just fine when called from repos in other Orgs of our enterprise. And I have runners setup for my repo that use the same labels being needed by the shared workflows I want to call.
