Getting a Dependencies installation error when previewing a deploy. I have no issues when building locally. I initially though it was something with @netlify/plugin-nextjs v3.2.0 since another project I have error-free and is running v3.1.0. But downgrading didn’t fix it.
Between the error message and the fact it runs on Vercel I assume it is a Netlify problem which I cannot seem to resolve—also building my code takes 15 mins…
Here is the section of the build log with the error (scroll in the box 
)and package.json:
