[ERROR] Top-level await is not available in the configured target environment ("node14")

I am getting an error that I’m using a feature not supported in Node v14. However, I’m not using Node v14, but v16. I have selected version 16 in every way I could find from the docs.

cat netlify.toml
[functions]
  node_bundler = "esbuild"
  external_node_modules = ["pg"]

[build.environment]
  NODE_VERSION = "16"
  AWS_LAMBDA_JS_RUNTIME = "nodejs16.x"

[context.production.environment]
  NODE_VERSION = "16"
  AWS_LAMBDA_JS_RUNTIME = "nodejs16.x"

[context.deploy-preview.environment]
  NODE_VERSION = "16"
  AWS_LAMBDA_JS_RUNTIME = "nodejs16.x"
cat .node-version
16

So why does it think I want Node v14 still?

Hi @acarl005,

Netlify Functions (AWS Lambda), still supports only Node 14 as the maximum value.

Hi @hrishikesh , thanks for the response. I see that Node v16 is only very recently supported by AWS Lambdas. Do you know if there is an estimated release date for Node v16 in Netlify functions?

I was aware that AWS was planning to launch that by mid-May, but missed the launch announcement. In any case, there’s no additional config that Netlify needs to do and you can use Node 16 by adding the following environment variable in your Netlify UI:

AWS_LAMBDA_JS_RUNTIME, value: nodejs16.x

I tried redeploying, but I’m still getting the same error. It is still trying to use Node v14.

I’m pretty confident I set the config necessary to select Node v16.

I added the env variable in the Netlify UI:

Here is my netlify.toml

[functions]
  node_bundler = "esbuild"
  external_node_modules = ["pg"]

[build.environment]
  NODE_VERSION = "16"
  AWS_LAMBDA_JS_RUNTIME = "nodejs16.x"

[context.production.environment]
  NODE_VERSION = "16"
  AWS_LAMBDA_JS_RUNTIME = "nodejs16.x"

[context.deploy-preview.environment]
  NODE_VERSION = "16"
  AWS_LAMBDA_JS_RUNTIME = "nodejs16.x"

And my .node-version file

16

The site seems to be deleted. Are you still having issues?

Oops. I forgot to mention I deleted the old site and created a new one to see if that could fix the issue.

Site name: sql-scholar
Site ID: 8195a125-53d2-49e3-84fa-f4ae1c2f9259

According to your deploy logs, this error seems to be gone. Do you still need help?

Yes, I still need hep. I removed a code path to get it deployed. But the problem is still there, and I still need it to run on node v16. It last occurred on this build:

Hi @acarl005,

Could you specify what exactly it is that you removed? That could have some clues as to what’s going on.

Also, if you can share a minimal reproduction of the one with the error, we could also debug it on our end.
