It seems that I found a weird bug. When I use one Form from the |Form Activities|, everything is fine. I extract data from JSON, and I can do my thing. However, when I want to use another form and extract JSON data, I get the “can’t convert string to integer” Error. And here is the weird part. If I delete the first form, the second form has no errors. If I disable the first form, the error is still there.
I wonder if any of you guys know how to help or have the error your self.
