Console logging not logging variables in Maestro

While debugging API calls I'm making in a script within a Maestro flow, I've discovered that console.log(), which is supported in Maestro as of 1.26.1, doesn't seem to be working as expected - the variable passed in as a second parameter in the example below doesn't log, even if the variable is declared right before the console.log:

const myValue = 'hey'
console.log('My hardcoded value is:', myValue) // only logs 'My hardcoded value is:'

Does anyone know what I'm doing wrong/of a way around this?

Solution

  • It turns out that the answer to this lies in, as the docs state,

    Maestro supports a minimal subset of vanilla JavaScript APIs

    Maestro is running a very limited version of JS, and one of the things that's unsupported is the console.log(msg, obj) syntax of console.log.

    So

    console.log('My variable', myVariable)

    fails, but if you do:

    console.log(myVariable)

    it works.

    (Update: Maestro now has beta support for GraalJS, which may also resolve the issue.)
