I have a json response from Web Api component. What could be the correct way to populate a empty list with the 5 elements (could be any number) of selPer property?

Text:  
{“seID”:“3b97189c-c766-4ce9-89de-bb2182157a76”,“sePer”:[“MAG041126GT8”,“POM030403GG2”,“SEG970227BQ2”,“SME0905211XA”,“SOL021205B49”,“SSE090521HN6”]}

Thanks

I made this demo screen

When starts call the web API

Receive a Json result

I read the sePer property of json to app variable called json\_rfc and show the result in a Text Input component  
 ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/4/3/43c727937d1f661959dea78944b232f4fbededd7.png)

When I try to make the list from the variable json\_rfc does not works

 ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/e/c/ecfcc7f1c75c6b119641a1fb6ccd1bde11be4ea1.png)

But when I make the list from the Text Input text its works fine

 ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/d/f/df536dfde9c575a4d6693d40d8993b13b5c7dd0b.png)

You have an error in the blocks, because you’re trying to JSON from a list to make another list. The variable “app json\_rfc” you have is a list. You get it?

Brackets indicate that you have an array (list) of nodes
