[lenkaiser]

When using the await pilot.perform method and one of the instructions is unable to find the component described by the prompt you'll get an error for str.slice is not a function. The str variable is actually the error:

Attempt 2/2 failed for step: Go to login screen via Setup my device button, with error: str.slice is not a function

Callstack:

    TypeError: str.slice is not a function
