Missing 'selector' for is_visible

Error message

Missing 'selector' for is_visible

What it means

Browser action parser guard: an 'is_visible' action was requested without its mandatory 'selector' argument, so there is no element to check visibility of. Fires in parse_browser_action before any browser command is issued.

Solutions

1. Include a 'selector' string in the is_visible action arguments
