forms.json empty?

Hi, I’ve just got my first static website up and running with simply static.
Really awesome work, thank you so much.

I do have a question. I’ve activated the use forms setting, and have created a form entry by following your tutorial. I’m using Gravity Forms.

However, my static form isn’t working yet (no error, just a spinner image svg 404). I think it might have something to do with the forms.json still being empty?

In my local environment the file has only the default values in it, so not the values I’ve filled in in WordPress. Does anyone know if this is a bug, or am I doing something wrong?

Thanks in advance.
