Boolean input does not meet YAML 1.2 "Core Schema"

[pantelis-karamolegkos]

I have a reusable workflow (i.e. triggered by the workflow_call event)

I also have the following input defined in it:

      do_something:
        description: whether to do something
        required: true
        type: boolean
        default: false

I use the github actions script to invoke a script from a separate file as instructed here, passing the core package as input

      - name: checkout the project
        uses: actions/checkout@v2

      - uses: actions/github-script@v6
        id: set-images
        with:
          script: |
            const script = require('./.github/workflows/myscript.js')
            console.log(script({core}))

Here is myscript.js

module.exports = ({core}) => {
    console.log(core.getBooleanInput['do_something'])
    return 0
}

This comes from the documentation of core package found here.

However this attempt fails:

TypeError: Input does not meet YAML 1.2 "Core Schema" specification: do_something
Support boolean input list: `true | True | TRUE | false | False | FALSE`

Same for me

Any news ?

core.getInput is for action inputs, it doesn't read workflow inputs. I suspect this error is occurring due to the do_something input being undefined.

You could workaround this in a few ways:

Use an environment variable

      - uses: actions/github-script@v6
        id: set-images
        env:
          DO_SOMETHING: ${{ inputs.do_something }}
        with:
          script: |
            const script = require('./.github/workflows/myscript.js')
            console.log(script({core}))

And then read that value in your script:

console.log(JSON.parse(process.env.DO_SOMETHING.toLowerCase()))

The JSON.parse should give you a boolean, but it would have unexpected results for non-boolean values.

Use an input variable

Warning
This may add a warning that the input isn't part of actions/github-script

      - uses: actions/github-script@v6
        id: set-images
        with:
           do_something: ${{ inputs.do_something }}
          script: |
            const script = require('./.github/workflows/myscript.js')
            console.log(script({core}))
         

The script should work as-is.

Use an environment variable and match the format of input

Action inputs are just input variables in a special format
https://github.com/actions/toolkit/blob/ffb7e3e14ed5e28ae00e9c49ba02b2764d57a6b7/packages/core/src/core.ts#L127-L128

I think we could use an env variable and fake it as an input. This would allow your script to remain unchanged but I don't know if it will get rid of the unrecognized input warnings.

      - uses: actions/github-script@v6
        id: set-images
        env:
          INPUT_DO_SOMETHING: ${{ inputs.do_something }}
        with:
          script: |
            const script = require('./.github/workflows/myscript.js')
            console.log(script({core}))
