Error creating publish and functions directories for production build

[MikeM2343]

Describe the bug

1. The build fails on the netlify server saying that the Web/out_functions and Web/out_publish directories do not exist
2. The netlify build process never finishes (stays at "building"), requiring you to "Cancel Deploy"

To Reproduce
Steps to reproduce the behavior:

1. Mono repo containing libraries and the main web app
2. Trigger the deploy that runs a script in the root of the repo that builds the libraries and then builds the main Next app

Expected behavior
The app builds without any errors

Versions

• Next.js: 10.0.8
• plugin (if installed at fixed version): 3.0.3

If you're using file-based installation
**netlify.toml: **

[build]
  command   = "yarn lerna run build"
  functions = "Web/out_functions"
  publish   = "Web/out_publish"

[dev]
  functions = "Web/out_functions"
  publish   = "Web/out_publish"
  autoLaunch = false
  command = "yarn run dev"
  targetPort = 3000
  framework = "#custom"

  [[plugins]]
  package = "@netlify/plugin-nextjs" 

Failed Build file
NetlifyBuild.log

Hello,

I'm not sure I have the correct netlify.toml configuration for the monorepo. I'm pretty sure I shouldn't be specifying a base directory because I need to run a script to build both my libraries and the main app from the root of the repo.

Is there any way to test this locally? I know that when using next-on-netlify, and doing a build, the out_publish and out_functions directories were created on my local system.

Thanks,
Mike

I've done a bit more digging and here's what I've found

• the Netlify deploy was not picking up the @netlify/plugin-nextjs plugin from the toml file in the Web directory as per the structure below
• When I added the netlify plugin via the Netlify UI and reran the deploy, I got a different error as indicated in this log:
  NetlifyBuild2.log
• I tried running "netlify build" locally. With debugging, I found that the plugin.onBuild was passed the proper PUBLISH_DIR, and FUNCTIONS_SRC constants (Web\out_publish and Web\out_functions) as per the toml file, but that the publish and functions properties of netlifyConfig had an extra 'Web' directory part in it. i.e. <rootDir>\Web\Web\out_publish. This may not be the case in a web-based deploy, but it does seem to be the case for a local 'netlify build'. The netlifyConfig object also had 'base' set to <rootDir>\Web. I have not set the "base" property of the netlify.toml or in the Netlify Web UI because I need to run the build script from the root directory.

My monorepo directory structure

/
| -- libs/
|    | -- lib1
|    | -- lib2
|    | -- ...
| -- Web/
|    | -- src/
|    | -- netlify.toml
|    | -- package.json 
| -- package.json (for lerna stuff)

The 'yarn lerna run build' builds all the libraries in libs and lastly runs yarn build in the Web directory, which runs 'next build'

hey @MikeM2343! thanks for your patience on this. we're finally getting to work on these greater monorepo issues. we're consolidating everyone's issues into #433, so we'll close this in favor of that. please follow along there, but we'll try to circle back here, too, whenever we release support! 🙏
