Supporting pnpm workspaces

Hey team!

I am in the process of automating my monorepo's deployment, up until now I have used Visual Studio codes inbuilt support for deploying to azure function, this process does npn install && npm run build basically. However I am using pnpm's workspace feature as I plan on sharing my backend validation with my frontend via a shared package that both can import.

The issue here is when I try to use pnpm install and pnpm run build, it results in a node_modules folder being created outside of the folder which contains my Azure Functions and thus my package: ./app/backend I can only assume will now miss the node_modules located in my pnpm store (it's centralised on the build machine and use sym links im pretty sure)

I would love to provide more info on the exact issue that the azure function ran into when built via pnpm, but the issue is cryptic giving me only:

Exception while executing function: Functions.Upload Result: Failure
Exception: Worker was unable to load function Upload: 'Unexpected token '.''
Stack: /home/site/wwwroot/node_modules/parse-multipart:1
../../../node_modules/.pnpm/parse-multipart@1.0.4/node_modules/parse-multipart

I have tried pnpm i --shamefully-flatten --force however this for whatever reason also didn't work either ;(

Has anyone managed to get pnpm in workspaces working for azure functions + this github actions? Heres a guy with what looks like a similar issue https://stackoverflow.com/questions/74944668/how-to-deploy-azure-function-with-pnpm-and-rush
