@bitter-branch-40324 yes it really works from your template. Thanks a lot for your efforts to help 🙂 1) BUUUUUUUUUUT, it still does not print it as a JSON (you see it has no '{' and '}' symbols) But in Playground it adds '{' and '}' Such instability is confusing. My idea is to send this result to JS script to parse but now it's not possible. 2) I checked every variable in my flow 20 times but cannot see a mistake 🙂 You can check my template if You have a time capacity
