File not found during Action runs

[threepistons]

• Given: the attached action YAML file located in .github/workflows/main.yml of my repo.
• When I: push to my repo.
• In order to test the Get SAML Identity Action.
• I expected: the Action to run and return either one SAML identity for threepistons, or else many SAML identities for the user's in the organisation. (Which of those two behaviours would result is one of the things I am trying to determine.)
• I get: a failed job and File not found: '/home/runner/work/_actions/gagoar/get-saml-identity-action/0.9.0/dist/index.js' in the detailed output of the job.

Have I made a mistake in my YAML file?

I examined this problem further.

• Given: the attached action YAML file located in .github/workflows/main.yml of my repo.
• When I: push to my repo or otherwise trigger the Actions in that file.
• In order to list the contents of ${{ github.workspace }}/../../_actions/gagoar/get-saml-identity-action/0.9.0/
• I expected: the ls command to show me a dist directory in 0.9.0, which in turn would contain index.js.
• I get: no dist directory shown in the run logs:
