Please see the circled area of my code, and the Build error message. I have commented out the open() statement but I am still getting an error on that line of code! Is there a workflow step I have missed to tell the IDE I have made a change and it should re-read and re-build the code? I am clicking on the Build (gear) icon.

Second question: so open() is not supported. Is there an alternative way to read a data file? Or do I have to use the “object store” ?  In this case I am accessing a CSV file represent forex calendar events.
