Parser error? - Unexpected token ':' at new AsyncFunction

[sgarciajaramillo]

Hi there,

I'm going over a set of inputs and checking which are set to true to eventually feed them to another workflow. Running the code below work fine out of actions. i.e (https://www.typescriptlang.org/play)

When I running with the action, I get the following. I've tried a few things but can't get any more detail.

Thanks for your help, sorry if I cannot provide much detail beside this.

              var services: string[] = []
              validate.forEach((value: boolean, key: string) => {
                if (value === true) {
                  services.push(key)
                  console.log(key)
                }
              });
              console.log(services)

Update: I think there is something wrong with the parser, this does not work either, I get the same error:

Run actions/github-script@v6
  with:
    script: 
  var services: boolean = true
  
  console.log(services)
  
  
  ERROR:
... 
SyntaxError: Unexpected token ':'
...

Ended up replacing that line with:

var services = Array.from(validate.entries()).filter(entry => entry[1]).map(entry => entry[0])

and got me going.

Thanks!

👋 @sgarciajaramillo this action doesn't support TypeScript syntax. In JavaScript, something like var services: string[] = [] or var services: boolean = true isn't valid. You should be able to remove the : Type from the variable declaration.

Looks like you're unblocked, so going to close this issue.
