http-request-action | Create HTTP Requests in GitHub Actions | REST library

I'm new to GitHub Actions (and yaml syntax) so I may be misunderstanding something about the ability to pass data between jobs: I've been trying to use a workflow with two jobs:

1. authenticateWithAuth0API asks for a token to be generated
2. triggerNetlifyFunction uses the token to authenticate with a Lambda function

For the first job, I can see that I do get back some kind of response that is saved as an output. The logs show the response is an access token with value ***. I assume the value appears as asterisks in the logs because the runner understands this value to be sensitive (a secret - though not a GitHub Secret).

I was under the impression that I could declare this as an output (which seems to go through ok) and then use it in the next job with the "needs" context. I'm using it as the value to the "Authorization" header for a call triggered in the next job.

However, in the logs I can see that the value of the header is empty showing up as Authorization:"". Am I missing something in terms of the ability to pass sensitive variables between jobs?
