2. Run yarn install locally
3. Test that the website builds locally with yarn dev ✅
4. Commit and push the changes made to package.json and yarn.lock
5. The automated unit tests fail ❌

The website builds locally but this error occurs when validating a feed:

If someone has some tips, feel free to help 🙏 Thank you!

EDIT: The error described above was due to my local env, not to the netlify-cli version.

I can have a look @richfab

I was able to pin the error in the install step down to the upgrade from v13 to v14, but can't really understand why.

The website builds locally but this error occurs when validating a feed:

This happens even in master. I think the problem is that you have to authenticate with netlify for this to work.

Very strange, the unit tests passed with v13 here https://github.com/entur/gbfs-validator/actions/runs/6671621967/job/18133905807

In my previous local tests, the argument -- filter website was causing the feed validation error.

Here are the next steps I took:

1. Used @testower tests in Incremental upgrade #146 to see that ^13.0.0 is the first major version that does not include static-server.
2. Set netlify-cli dependency to ^13.0.0 in devDependencies in package.json
3. Run yarn install locally
4. Test that the website builds locally with yarn dev ✅
5. Commit and push the changes made to package.json and yarn.lock
6. The automated unit tests fail ❌

The unit tests seem to fail when trying to install esbuild https://github.com/MobilityData/gbfs-validator/actions/runs/6695935881/job/18195967695#step:4:48.

Due to the low priority of this issue (#134 (comment)), I will close this draft PR for now.
