"bad substitution" error running action

[krisalyssa]

I don't know how much I can paste here, as the error comes from runs in a private repo.

We're invoking it like

  gitStream:
    timeout-minutes: 5
    runs-on: ubuntu-latest
    name: gitStream workflow automation
    steps:
      - name: Evaluate Rules
        uses: linear-b/gitstream-github-action@v1
        id: rules-engine
        with:
          full_repository: ${{ github.event.inputs.full_repository }}
          head_ref: ${{ github.event.inputs.head_ref }}
          base_ref: ${{ github.event.inputs.base_ref }}
          client_payload: ${{ github.event.inputs.client_payload }}
          installation_id: ${{ github.event.inputs.installation_id }}
          resolver_url: ${{ github.event.inputs.resolver_url }}
          resolver_token: ${{ github.event.inputs.resolver_token }}

(I think this is boilerplate from your documentation.)

The error is coming from this step in the action:

  env_file=env.user
  touch $env_file
  for var in $(env | cut -d "=" -f 1); do
    value="${!var}"
    echo "$var=$value" >> "$env_file"
  done
  docker pull gitstream/rules-engine:latest
  echo "docker-pull-duration=$SECONDS" >> $GITHUB_OUTPUT
  SECONDS=0
  docker run --env-file $env_file -v $(pwd)/gitstream:/code -e USE_CACHE= -e HEAD_REF=... -e BASE_REF=main -e CLIENT_PAYLOAD="{...}"  -e RULES_RESOLVER_URL=https://qembo8hwr6.execute-api.us-west-1.amazonaws.com/prod/api/v1/gitstream/resolve -e RULES_RESOLVER_TOKEN=... -e DEBUG_MODE= gitstream/rules-engine
  echo "docker-run-duration=$SECONDS" >> $GITHUB_OUTPUT
  echo "action-run-duration=$(($EPOCHSECONDS - 1686844604))" >> $GITHUB_OUTPUT

where the value of CLIENT_PASSWORD is very large (10365 characters).

Please let me know if there is any other information I can provide.
