IDK... you can debug the Netlify docker build locally apparently, might try that later https://github.com/netlify/build-image#testing-locally

[KyleAMathews]

Looks like a bad node_modules cache where pngquant is missing

[alexkrolick]

Nuking the cache before every build seems reasonable given how many problems we've had with it

Thank you!
