Output of relativePoint cannot be used with swipe command start and end parameters

[tafty]

Is there an existing issue for this?

• I have searched the existing issues and didn't find mine.

Steps to reproduce

The output of the relativePoint JavaScript function can be passed into the tapOn command as the point parameter but cannot be passed into the swipe command as either the start or end parameters.

For example, the below works as expected with tapOn:

- evalScript: ${output.startPoint = relativePoint(0.5, 0.8)}

- tapOn:
    point: ${output.startPoint}

But using the same variable with swipe gives a runtime error when starting the Maestro script:

- evalScript: ${output.startPoint = relativePoint(0.5, 0.8)}

- swipe:
    start: ${output.startPoint}
    end: 50%,12%

The error shown is:

You need to provide start and end coordinates with %, Found: (50%, 12%, ${output.startPoint})

There's nothing in the docs to indicate that the output of relativePoint shouldn't be used with the swipe command. Am I doing something wrong? I guess the error implies that the inline JavaScript value is not being evaluated correctly for the swipe command...?

Actual results

Maestro script does not run and gives error: You need to provide start and end coordinates with %, Found: (50%, 12%, ${output.startPoint})

Expected results

The JavaScript variable is evaluated correctly to it's point coordinates and passed into the swipe command.

How did you install Maestro?

Anything else?

The use case associated with this issue is that I have a utility YAML file that scrolls down a long screen and takes screenshots of each section. I need to be able to pass in a parameter for the start percentage of the swipe because some screens have tabs at the bottom whilst others do not. Passing a parameter into relativePoint also fails with the same error but I've boiled my example down to the simplest representation of the problem.
