I have figured out that the error " Unknown Syntax Error: Unsupported option name (“–no-ignore-optional”)." occurs because Yarn 3.0.2 no longer supports the --no-ignore-optional option. I’m not sure how Netlify is using this flag or where to unset it in Netlify.
Here is a GitHub issue on yarn berry that says yarn no longer supports this option. What happen to --ignore-optional? · Discussion #2412 · yarnpkg/berry · GitHub
I was able to reproduce this issue on my local system with yarn 3.0.2 by running yarn install --ignore-optional
Now, where can I change this in Netlify so that option is not used during Netlify build?
