Can't use multiple line val in env_vars

[onel]

TL;DR

I'm trying to deploy to cloud run and one of the env_vars has a value that is multi line, specifically it is a PEM key.
This seems to make the key not be used properly in cloud run UI.
The problem is with GH_APP_PRIVATE_KEY
Tried with with both "" and without.

In the google console UI the output looks like this

This might be a yaml question more than a deploy-cloudrun one.

Expected behavior

Observed behavior

Action YAML

- name: Deploy to Google Cloud Run
        uses: google-github-actions/deploy-cloudrun@v2

        with:
          service: ${{ env.RUN_SERVICE }}
          image: ${{ env.GAR_LOCATION }}
          region: ${{ env.REGION }}

          env_vars: |-
            DEBUG='False'
            GH_APP_PRIVATE_KEY=${{ secrets.GH_APP_PRIVATE_KEY }}

Have you tried:

env_vars: |-
  GH_APP_PRIVATE_KEY="${{ secrets.GH_APP_PRIVATE_KEY }}"

If so, please provide the debug logs.

Yes, I've tried with quotes as well.

This is the log output specifically for the deploy job (the link expires in 1 week)

Pasting the relevant bits here for history:

GH_APP_PRIVATE_KEY="***,***=,***=,***=,***=,***=,***=,***=,***=,***=,***=,***=,***=,***=,***=,***=,***=,***=,***=,***=,***=,***=,***=,***=,***=,***=,***"= 

It looks like parsing is actually successful, but then re-serialization is incorrect.

I see, so this might be a deploy-cloudrun bug?
