I was able to fix this by setting NODE_VERSION to 22.4.1 in my project’s environment variables. Posting here in hopes the Render team will roll back to 22.4.1 until the issue with 22.5.0 is patched.
Render will use the version of NodeJS you specify: https://docs.render.com/node-version. If you don’t specify a version, our default is 20.15.1. How we detected the NodeJS version should be listed in your build logs.
Got it. I was confused because I hadn’t made any configuration changes and yet my app suddenly stopped building on Render. Turns out I had this in my package.json, so as soon as Node 22.5 became available on Render, the bug affected my build.
