503 Errors Once Deployed

I'm using the provided github workflow and Dockerfile, and the github action completes, but then my app returns a 503 error.

The action shows this warning:

And in the function app there are another couple of warnings: Storage is not configured properly, Function scaling will be limited. Click to learn more. We were not able to load some functions in the list due to errors. Refresh the page to try again. See details

Here's my Dockerfile:

FROM mcr.microsoft.com/azure-functions/python:4-python3.9

ENV AzureWebJobsScriptRoot=/home/site/wwwroot \
    AzureFunctionsJobHost__Logging__Console__IsEnabled=true

# Install Tesseract OCR and poppler-utils
RUN apt-get update && \
    apt-get install -y tesseract-ocr poppler-utils

COPY requirements.txt /
RUN pip install -r /requirements.txt

COPY . /home/site/wwwroot

And workflow:

  deploy:
    needs: build
    runs-on: ubuntu-latest
    environment:
      name: "Dev"
      url: ${{ steps.deploy-to-function.outputs.app-url }}

    steps:
      - name: Login via Azure CLI
        uses: azure/login@v1
        with:
          creds: ${{ secrets.AZURE_CREDENTIALS }}

      - name: Checkout repository
        uses: actions/checkout@v4

      - name: Set up Docker Buildx
        uses: docker/setup-buildx-action@v2

      - name: Log in to Azure Container Registry
        uses: azure/docker-login@v1
        with:
          login-server: ${{ env.AZURE_CONTAINER_REGISTRY }}
          username: ${{ vars.ACR_USERNAME }}
          password: ${{ secrets.ACR_PASSWORD }}

      - name: Build and push Docker image
        uses: docker/build-push-action@v4
        with:
          context: .
          file: ./Dockerfile
          push: true
          tags: ${{ env.AZURE_CONTAINER_REGISTRY }}/${{ env.AZURE_FUNCTIONAPP_NAME }}:${{ github.sha }}

      - name: Deploy to Azure Functions
        uses: Azure/functions-container-action@v1
        with:
          app-name: ${{ env.AZURE_FUNCTIONAPP_NAME }}
          image: ${{ env.AZURE_CONTAINER_REGISTRY }}/${{ env.AZURE_FUNCTIONAPP_NAME }}:${{ github.sha }}

      - name: Azure logout
        run: |
          az logout

Am I doing something wrong?

My connection strings haven't change since before I used Docker to deploy the app, so I don't think it's that.
