I think there's a problem in chrome. Is very difficult to make the codex model to work at all. At least for me.
Sometimes it works. Sometimes it only generates white spaces and other times makes a lot of '+' signs

I doubt that the issue is in any way related to your browser. I have no clue why that's going on, but I don't think the issue has anything to do with the browser you use for sandbox.

I haven't had the time to set up a proper project and access the api via code, but I hope this browser behavior doesn't translate to the api
