Is possible to run migrations in Pages build command?

I'm not sure what is the right flow to run D1 migrations... If I understand it correctly so far, you have to: Push migrations with a command: npx wrangler d1 migrations apply db-name as a wrangler command from the local env to make changes in the prod. DB and then push the changed app code (wich rely on new DB schema) to git. Shouldn't be a migration run right after the deployment in the "build command" like: npm run build && npx wrangler d1 migrations apply db-name Is this possible? I tried the comamnd and got the error:

In a non-interactive environment, it's necessary to set a CLOUDFLARE_API_TOKEN environment variable for wrangler to work. Please go to https://developers.cloudflare.com/fundamentals/api/get-started/create-token/ for instructions on how to create an api token, and assign its value to CLOUDFLARE_API_TOKEN.

After creating CLOUDFLARE_API_TOKEN env var I get this error:

The way I've tackled this issue is by using github actions to deploy and push to pages, and then run a command after which runs migrations This is my example preview deployment,yml

name: Preview Deployment

on:
  push:
    branches-ignore:
      - "main"

jobs:
  deploy-preview:
    if: github.actor != 'dependabot[bot]'
    runs-on: ubuntu-latest
    name: Preview Deployment
    steps:
      - uses: actions/checkout@v4
      - name: Deploy
        uses: cloudflare/wrangler-action@v3
        with:
          apiToken: ${{ secrets.CLOUDFLARE_API_TOKEN }}
          accountId: ${{ secrets.CLOUDFLARE_ACCOUNT_ID }}
          preCommands: |
            npm install
            npx @cloudflare/next-on-pages@1
          command: pages deploy --project-name=[PROJECT NAME] --commit-dirty
          postCommands: |
            echo "*** Applying Preview Migrations ***"
            npx wrangler d1 migrations apply [PROJECT NAME] --preview --remote
            echo "******"

name: Preview Deployment

on:
  push:
    branches-ignore:
      - "main"

jobs:
  deploy-preview:
    if: github.actor != 'dependabot[bot]'
    runs-on: ubuntu-latest
    name: Preview Deployment
    steps:
      - uses: actions/checkout@v4
      - name: Deploy
        uses: cloudflare/wrangler-action@v3
        with:
          apiToken: ${{ secrets.CLOUDFLARE_API_TOKEN }}
          accountId: ${{ secrets.CLOUDFLARE_ACCOUNT_ID }}
          preCommands: |
            npm install
            npx @cloudflare/next-on-pages@1
          command: pages deploy --project-name=[PROJECT NAME] --commit-dirty
          postCommands: |
            echo "*** Applying Preview Migrations ***"
            npx wrangler d1 migrations apply [PROJECT NAME] --preview --remote
            echo "******"
