Required authorization - 404 Error

[fiddlermikey]

Is there any troubleshooting I can do to get past this 404 error I am getting? I am trying to use a script in a repo to launch a reusable workflow in another repo which targets a third repo to download, modify, and replace the release zip file. Everything works until I attempt to check in the modified zip file using the release-action workflow.

I created a PAT for my user that gives full Repo access (private and public). I also created a secret for my Org called CODESIGN_TOKEN, the value was pasted from my PAT key and SSO was enabled.

Calling workflow passes the repo and the file that needs to be modified and the secret.token

jobs:
  call-sign-binaries:
    if: github.event_name == 'push' || github.event_name == 'workflow_dispatch'
    uses: ..../sign-binaries.yml@add-sign-process
    with:
      signFile: IntegrationSandbox.dll
      targetRepo: integration-sandbox
    secrets: 
      token: ${{ secrets.CODESIGN_TOKEN }}

The sign-binaries workflow gets called and a series of workflows and run statements continue until I get an error with this part of the workflow. Am I passing something incorrectly? Is my PAT setup incorrectly? Any help would be appreciated.

The repo is actually split across two arguments. You should specify owner and repo (they combine like this: owner/repo).
