Npm run build fails for my NextJs app

[arscroggin]

My npm run build command fails with these two errors even though it builds just fine using Render.com’s Shell feature. What gives?

Hi Adam,

One thing to keep in mind is that the shell you have access to in the dashboard is running the last successful build/deploy of your service. So if something changed that broke the build process, it would not be present in the instance you’re accessing via the shell.

I’d suggest finding that last successful deploy and try rolling back to it to confirm it successfully builds again. Then inspect the diff between the successful and failing build.

Feel free to let me know if I can answer any other questions about this for you.

Regards,

Matt
