GitHub Actions expressions property dereference output name hyphen steps.outputs.exit-code continue-on-error outcome

💡 Result:

In GitHub Actions, using dot notation (e.g., steps.my-step.outputs.my-output) for step IDs or output names that contain hyphens will cause expression evaluation failures [1]. This occurs because the expression evaluator interprets the hyphen as a subtraction operator rather than part of the identifier [2][1]. To resolve this, you must use bracket notation (index syntax) to reference the property [2][1]. For example, if you have a step with an ID of my-step and an output named exit-code, you should access it as follows: ${{ steps['my-step'].outputs['exit-code'] }} This ensures the string is treated as a literal key rather than a mathematical operation [3]. Regarding continue-on-error and outcome: The steps context provides both an outcome and a conclusion for each step [4][5]. - steps.<step_id>.outcome: Contains the result of the step before the continue-on-error setting is applied (e.g., success, failure, cancelled, or skipped) [4][5]. - steps.<step_id>.conclusion: Contains the final result of the step after the continue-on-error setting is applied [4][5]. If a step has continue-on-error: true and it fails, the outcome will be failure, but the conclusion will be success [4][5].

Fail on scanner errors while keeping findings advisory.

Job-level continue-on-error hides Trustabl exit code 2 and other action failures. Move it to the Trustabl step and add a follow-up check. Use steps.trustabl.outputs['exit-code'] because exit-code requires bracket notation. Allow exit code 1, but fail for exit code 2, missing output, or other failures.

from the job level to the Trustabl step, then add a follow-up validation step
that checks steps.trustabl.outputs['exit-code']. Treat exit code 1 as advisory,
but fail the job for exit code 2, a missing output, or any other Trustabl/action
failure.
