The second argument to foreach is not a list. The second argument is: ""

I have these blocks to search by name and filter the search. I have a php file that does the lookups and then pass them to a json array. When searching by name I have the error of the title.

What is wrong with the blocks?

Where are you sending a url ?
Put responseContent into a label, then see what, if anything, is coming back from your server.

I have the url of the file in the design part. Sorry, I didn't understand how to put the reply content on a tag


the next error that I get is: "The arguments are the wrong number for JsonTextDecode"

please show us your Do it result of the Etiqueta1.Texto as @TIMAI2 already explained
