The Static Web App contents cannot be updated while a backend migration is in progress

Question

When attempting to deploy via an Azure DevOps pipeline or the SWA cli we get the error:

The content server has rejected the request with: BadRequest
Reason: The Static Web App contents cannot be updated while a backend migration is in progress.

It was working fine for months until we added an API (Azure managed), first deployment worked and then all deployment since have failed with this error message.

Answer 1

I have encountered the same issue. This is what i have done to fix it. It's a bit lengthy but does the job.

• Delete the existing app through azure cli (or create a new one - step 2).

az staticwebapp delete--name <app_name> -g <resource_group>

• Create a new app with no github integration etc.

az staticwebapp create --name <app_name> -g <resource_group>

• Fetch the deployment token using the following command

az staticwebapp secrets list --name <app_name> --query "properties.apiKey"

• Modified my github actions to use swa cli instead of the official github action - Azure/static-web-apps-deploy@

 - name: Install Azure SWA CLI
   run: npm install -g @azure/static-web-apps-cli

 - name: Deploy 
   run: |
      swa deploy <app_location> \
      --api-location <api_location> \
      --env <env> \
      --deployment-token <deployment_token> \ 
      -name <name_of_the_app>

Note: You can use the the official github action - Azure/static-web-apps-deploy@ to do deployment too but i haven't tested it. So, cannot confirm if it will work. I prefer this way.
