Generally, libraries that choose to fail on warnings presume their users will want to fix the issues causing the warnings. If this isn’t practical for your use case, you can override the CI variable by adding CI='' to the beginning of your site build command. For example:

CI='' npm run build

This fixed my own similar problem
