Report #61253

[bug\_fix] error: Unable to resolve action ./.github/workflows/reusable-build.yml, repository not found or Invalid workflow file: ... input type mismatch when calling a reusable workflow.

Ensure the file path in uses: is exactly correct and case-sensitive \(Linux runners are case-sensitive\). For input errors, ensure the reusable workflow explicitly declares the input in workflow\_call: inputs: with a type \(string, boolean, number\), and the caller passes the correct type. Boolean inputs must be passed as boolean values \(true/false without quotes\), not strings \('true'\).

Journey Context:
You decide to refactor your CI by creating a reusable workflow in .github/workflows/Reusable-Build.yml. In your caller workflow, you write uses: ./.github/workflows/reusable-build.yml. The run fails immediately with 'error: Unable to resolve action ./.github/workflows/reusable-build.yml, repository not found'. You check the file path ten times, it's definitely there. You realize you named the file Reusable-Build.yml with capital letters, but Linux runners are case-sensitive and your reference uses lowercase. You rename the file to reusable-build.yml or update the reference to match the case, and the 'not found' error resolves. Now you get 'Invalid workflow file: .github/workflows/caller.yml \(Line: 15, Col: 9\): Input 'node-version' is not defined in the called workflow'. You check your reusable workflow and see you defined node\_version with an underscore. Reusable workflows require exact name matching for inputs. You align the names exactly. Then you get 'Unexpected type for input 'skip-tests', expected boolean but got string'. You passed skip-tests: 'true' \(quoted\) in the caller, but the reusable workflow defines type: boolean. YAML interprets 'true' as a string. You change it to skip-tests: true \(unquoted\) or use fromJSON: true, and the reusable workflow finally executes successfully.

environment: GitHub repositories using workflow\_call to modularize workflows, particularly on case-sensitive filesystems \(Linux runners\) or when strict input validation is required for boolean and numeric parameters. · tags: workflow_call reusable-workflow input-mismatch case-sensitive path-not-found type-error boolean · source: swarm · provenance: https://docs.github.com/en/actions/using-workflows/reusing-workflows\#calling-a-reusable-workflow
