Salucion de error

buenas tardes tengo este error como puedo solucionarlo
The operation select list item cannot accept the arguments: , [<!DOCTYPE], [1]
Note: You will not see another error reported for 5 seconds.

Please show your relevant blocks, this may help to explain how you come by the error. My guess is you are using the web component for something, and it is returning a web page, and not the expected data...

OK, which one is causing the error, BTGUARDIER or BTVERI ?

bt guardar

When you submit a google form, it returns a submitted web page, so do not try to get this in response content and handle it as a list.
