I think I missed a detail somewhere - I'm trying to start the frontend with "npm start" but got this result:

> frontend@0.1.0 start
> sst-env -- react-scripts start

sst-env: Cannot find matching SST environment outputs in D:\Development\fasterbuddy\.build\static-site-environment-output-values.json. Ensure the StaticSite points to D:\Development\fasterbuddy\frontend

Where should I look to fix this? That output json file that is mentioned in the error message is actually empty.

Can you share your static site object?

Is sst start running?

Yes, I did have "sst start" running - but I stopped it and re-started it. "npm start" then worked as expected. Thanks for your help.
