Node version not being set using .nvmrc in root of monorepo or as NODE_VERSION envar

PLEASE help us help you by writing a good post!
My Netlify site name is boring-torvalds-ee9036.

I’m building and app with svelte-kit. The adapter for svelte-kit specifically indicates that svelte-kit won’t build with Node 12.16. So I have included a .nvmrc with 14 in it and I have attempted to set a NODE_VERSION envar to 14.

It appears from the logs that Node v12.16.3 is being used.

What am I doing wrong?

Just to check, you have specified NODE_VERSION as v14.17.1 (or whichever minor/patch version you wish to use)?

I have successful set the NODE_VERSION environment variable via the Netlify UI and had it picked up while using the latest build image in a test I have just finished.

Hi @robhicks,

Your latest logs suggest: Netlify App, that you’ve got this part working. Is that the case?

No, my builds are still failing. I have set the NODE_VERSION envar to 14.17.5.

The build fails when it gets to setting up functions.

Thanks for your help!

Can you share your full deploy log @robhicks

Yes, here’s a complete log.

Hi @robhicks

Functions need a different environment variable AWS_LAMBDA_JS_RUNTIME with the value nodejs14.x. Could you try that?

I tried adding the AWS_LAMBDA_JS_RUNTIME envar but the build still failed with the same error message.

Hi @robhicks,

Could you also try using esbuild to bundle the functions?

You could do so by adding the following to your netlify.toml:

[functions]
  node_bundler = "esbuild"

Thanks a lot! It solved my problem.
