Reposting S.Nadal post. I have same issue.
I was trying to use the cli for debugging the app locally instead of using Flutterflow Run.
This way debugging would be much faster than with the online tool and Flutterflow Team will save some extra $$ in servers / bandwith.
I managed to download my project's code a couple of times, buf after that I get a 429 (Too many requests) response.
Anyone at the FlutterFlow Team could tell me what is the maximum rate for using the cli?
