GitHub Actions is a powerful CI/CD tool integrated directly into GitHub, allowing developers to automate their workflows, from code testing to deployment. It provides a flexible way to build, test, and deploy applications directly from a GitHub repository.
One common issue developers encounter is a job failure due to missing input. This typically manifests as an error message indicating that a required input for the job is not provided. This can halt the workflow execution and prevent the job from completing successfully.
When this issue occurs, you might see an error message like:
Error: Input required and not supplied: <input_name>
The root cause of this problem is often a missing input parameter that the workflow expects to be provided. Inputs are defined in the workflow YAML file and are essential for the job's execution. If these inputs are not supplied, either through the workflow file or at runtime, the job will fail.
To resolve this issue, follow these steps:
Check the workflow YAML file to ensure that all required inputs are defined correctly. Inputs are typically defined under the jobs section. For example:
jobs:
build:
runs-on: ubuntu-latest
steps:
- name: Checkout code
uses: actions/checkout@v2
- name: Run script
uses: actions/setup-node@v2
with:
node-version: '14'
input_name: ${{ inputs.input_name }}
If the inputs are defined but not provided, ensure they are supplied when triggering the workflow. This can be done through the GitHub Actions UI or via the command line. For example, when using the GitHub CLI:
gh workflow run <workflow_name> --field input_name=value
Ensure there are no typographical errors in the input names. The input names in the workflow file must match exactly with those provided at runtime.
