An error like the above occurred.

.yarnrc.yml

nodeLinker: pnp

yarnPath: .yarn/releases/yarn-4.4.1.cjs

And this is my .yarnrc.yml file. Is there a mistake?

name: CI Workflow

on:
  push:
    branches: [main, develop]
  pull_request:
    branches: [main, develop]

jobs:
  build:
    runs-on: ubuntu-latest

    strategy:
      matrix:
        node-version: [18.x, 20.x]

    steps:
      - name: Checkout code
        uses: actions/checkout@v4

      - name: Set up Node.js ${{ matrix.node-version }}
        uses: actions/setup-node@v4
        with:
          node-version: ${{ matrix.node-version }}
          cache: 'yarn'

      - name: Enable Corepack
        run: corepack enable

      - name: Install dependencies
        run: yarn install

      - name: Run tests
        run: yarn test --passWithNoTests

      - name: Build project
        run: yarn build

And this may be helpful, but this is the project’s workflows yml file

I was building a CI for a project using yarn berry and github actions, but I got an error like a syntax error in the yarnrc.yml file. There doesn’t seem to be any syntax error, so what’s the problem?
