Im facing the following error Error: EACCES: permission denied, mkdir '/opt/hostedtoolcache/node' when running the workflow below

name: Deploy to Desenv

on:
  workflow_dispatch:
    inputs:
      runner:
        description: "Choose runner"
        required: true
        default: "self-hosted"
        type: choice
        options:
          - self-hosted
          - ubuntu-latest

env:
  NODE_VERSION: '20.x'

jobs:
  deploy-database:
    name: Deploy Prisma Migrations
    runs-on: ${{ github.event.inputs.runner }}
    environment: DESENV

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

      - name: Setup Node.js
        uses: actions/setup-node@v4
        with:
          node-version: ${{ env.NODE_VERSION }}
          cache: 'npm'

      - name: Cache dependencies
        uses: actions/cache@v4
        with:
          path: ~/.npm
          key: ${{ runner.os }}-node-${{ hashFiles('**/package-lock.json') }}
          restore-keys: |
            ${{ runner.os }}-node-

      - name: Install dependencies
        run: npm ci

this error do not occour when i run it on ubuntu-latest

i have found a solution using gemini by creating the toolcache directory before running the setup node action, the fixed workflow is

name: Deploy to Desenv

on:
  workflow_dispatch:
    inputs:
      runner:
        description: "Choose runner"
        required: true
        default: "self-hosted"
        type: choice
        options:
          - self-hosted
          - ubuntu-latest

env:
  NODE_VERSION: '20.x'

jobs:
  deploy-database:
    name: Deploy Prisma Migrations
    runs-on: ${{ github.event.inputs.runner }}
    environment: DESENV

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

      - name: Create Node.js toolcache directory
        run: sudo mkdir -p /opt/hostedtoolcache/node && sudo chown -R $(whoami):$(whoami) /opt/hostedtoolcache/node

      - name: Setup Node.js
        uses: actions/setup-node@v4
        with:
          node-version: ${{ env.NODE_VERSION }}
          cache: 'npm'

      - name: Cache dependencies
        uses: actions/cache@v4
        with:
          path: ~/.npm
          key: ${{ runner.os }}-node-${{ hashFiles('**/package-lock.json') }}
          restore-keys: |
            ${{ runner.os }}-node-

      - name: Install dependencies
        run: npm ci

gemini also suggested to make this changes, maybe doing this in the dockerfile fix the issue

The error EACCES: permission denied, mkdir '/opt/hostedtoolcache/node' on a self-hosted runner indicates that the user running the GitHub Actions runner process does not have the necessary permissions to create directories within /opt/hostedtoolcache/node. This directory is typically used by actions like setup-node to cache Node.js versions.
To resolve this issue, you need to grant the appropriate permissions to the user account that is running the self-hosted runner. Here are a few common solutions:
Change ownership and permissions of the /opt/hostedtoolcache directory:
Ensure that the user account running the self-hosted runner is the owner of the /opt/hostedtoolcache directory and has write permissions.

    sudo chown -R <runner_user>:<runner_group> /opt/hostedtoolcache
    sudo chmod -R 755 /opt/hostedtoolcache
