I have created this html page  
[https://www.tecnofuego.cl/encoder.html](https://www.tecnofuego.cl/encoder.html)

to use the following javascript

I try to get an sql query encoded, so I put the URL on the Web\_viewer component, but all I get as a response is “undefined”

I’m guessing you hosted the file as a local asset?
