filter [origin/main] not working in github actions

[AndyOooh]

Hi,

I'm trying to set up a CI pipeline which lints and builds any workspaces which have changes compared to the current remote main branch. For that I'm using --filter=[origin/main] as I have seen other people do. It works fine when I run it locally in my terminal but when I run it on github the remote branch is not found. This is my script:

EDIT for context:
main branch is protected with PR required, so this workflow triggers on all other branches. The flow is: branch out from main, commit changes and push to dedicated remote feature branch, the PR to main. This script is triggered on push to new remote feature branch.

name: Push to any
run-name: Build on push to any branch except main

on:
  push:
    branches-ignore:
      - main


jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@v3
        with:
          fetch-depth: 10
      - name: Install Node.js v18
        uses: actions/setup-node@v2
        with:
          node-version: '18.x'
      - name: Install TurboRepo CLI
        run: yarn global add turbo
      - name: Lint, Build, and Test
        run: |
          yarn
          turbo run lint --filter="...[origin/main]"
          # turbo build
          # turbo test (not implemented yet)

The error I'm getting:
ERROR run failed: failed to resolve packages to run: git error: revspec 'origin/main' not found; class=Reference (4); code=NotFound (-3)

I have tried several variations, e.g. --filter="...[origin/main]", --filter=[origin/main] etc.

What am I misssing?

From what I understand, it appears that that ref is not available in the action. Do you have another way of verifying that that ref is available and that turbo specifically is failing to find it?
