I am using the netlify adapter, and the project uses firebase.

I had the same problem recently and fixed it the following way:

Go to your Netlify account and select the site you want to build. Switch to “Site settings” > “Build & deploy” > “Environment variables”. With “Edit variables” add the following:

Key: AWS_LAMBDA_JS_RUNTIME
Value: nodejs14.x

Netlify deployment settings; environment variables: Key: AWS_LAMBDA_JS_RUNTIME, Value: nodejs14.x

Save and try deploying your site again. :)

The answer from Mue worked for me only after adding the following in my netlify.toml file (taken from the adapter-netlify README):

[functions]
  directory = "functions"
  node_bundler = "esbuild"
