good morning, the application that I am developing presents me with this error, although the answer is correct and the application fulfills its purpose, it generates this error at the end of the process
the text that results in etqproductname is correct and when sending the data to the google sheets file it sends them correctly but I still can't understand what is the cause of that error
As suggested, look at the entire responseContent being returned. It is most likely an html page generated by a problem with your google apps script. A description of the error should be near the end of the html.
It is possible that the application ignores that error simply so that it does not appear on the screen, the application works correctly, but every time I try to save the information, it shows me this message, I just need to make it not show that, is there a way to do it?
