Express program buiild failed

Support
1

Hi, I run into a problem recently, my express service worked fine on netlify before, and last commit I changed some business code, then cannot build success ever!

This is my site: tc-backend.netlify.app
And below is the build log(remove some content because of word count limit), I have checked it, found error when netlify-lambda build express, seems is about ‘webpack’, but this is a nodejs service, I haven’t install ‘webpack’, and the package-lock file shows thenetlify-lambda package required ‘webpack’, now I have no clue how to fix this. can anyone please lend me a hand?

Heya, lvsong, welcome to the netlify community !

This seems like an issue with your
config maybe, it’s trying to build
netlify functions (read more here) in node_modules, maybe you
misconfigured it ?

Please check your netlify.toml potentially, your functions dir should not be set to node_modules, read more about file-based configuration here :slight_smile:

Thanks for reply so soon!

This is my netlify.toml file:

[build]
  command = "npm install && npm run build"
  functions = "functions"

It works fine before.

Please check my github repository if you may, this is a really tiny project, and I used the simply config for netlify.

4

Thanks for sharing the repository @lvsong77. Unfortunately it is private. Can you make it public?

There is no need for npm install as part of the command. Netlify automatically installs packages listed in the package.json.

5

I have trun this repository to public, may you check again?

And I already have try command without npm install, but failed also.

I have (sort of) got it working locally using Netlify CLI (sort of because I don’t have the required credentials.)

These are the changes I made:

  • Remove the build script from package.json
  • Remove the command from netlify.toml
  • Change functions = "functions" to functions = "express" in netlify.toml

Then I ran netlify dev --offline and was able to load the function (which displayed hello world) in a browser.

Try making the above changes, and ensure the build command in the Netlify Dashboard is also blank. I suggest also making a directory called site with a blank index.html and setting this as the publish directory.

Thank you very much for help!

This works fine now!
