Hi Fidel,
you should find the latest version here: Tinderbox and the OpenAI API - #70 by TomD
By default the file writes a log when using the ChatGPT API (in gPreferences you can switch the log off). See the note “debug” for the output. This should help a lot when looking for the problems with the API.
And there is a ReadMe! note (the 1st note) with some help too.
