The bot fails with "filename argument required" on yarn 3 monorepo

[dmitriy-kudelko]

How are you running Renovate?

Mend Renovate hosted app on github.com

If you're self-hosting Renovate, tell us what version of Renovate you run.

No response

If you're self-hosting Renovate, select which platform you are using.

None

Was this something which used to work for you, and then stopped?

I am trying to get this working for the first time

Describe the problem

Hello, dear Renovate maintainers!

We're trying to migrate one of our repos to yarn-based monorepo. For this purpose we used latest yarn 3.6.1 with nodeLinker: node-modules and zero installs enabled (all deps are stored in archives under .yarn/cache folder).

Another, possibly important detail, is that we have to use Node.js 14, since it's required by one of our dependencies.

A problem however is that after migrating to monorepo all renovate bot PRs now fail with the same error (see the logs).

I've created a minimal reproduction repo here: dmitriy-kudelko/flex-plugins#3

Could you please have a look what might be wrong?

Interestingly, a somewhat similar error happens when trying to validate the config locally via renovate-config-validator:

    at Module._compile (internal/modules/cjs/loader.js:1114:14)

And it doesn't occur when switching to Node.js 18 locally. So these might be somehow related.

Our previous monolithic repo also relied on Node.js 14, and renovate bot worked just fine. So I assume it's something related specifically to how yarn repos with older Node.js versions are handled

Have you created a minimal reproduction repository?

I have linked to a minimal reproduction in the description above

Corepack not supported in node 14?

[dmitriy-kudelko]

So guys, do you want me to open this PR? I just planned looking at it but, it turned out the fix is already there :)
Or do you still need to discuss if this solution is a proper one?

[rarkins]

I'm on vacation and on mobile so wont be continuing it- you're welcome to take my code and add a test in a PR!

[dmitriy-kudelko]

Alright, sounds like a plan! Will do.
