I have a static web app which is react code and a linux app service. I can browse both. Everything works. When I go to Static Web App > APIs > Production -> Link and select my Linux App Service, the container restarts and errors out with the following error (taken from log stream):

I've googled that last line and have found nothing helpful. If I unlink the static web app, remove the authentication setup it created, and restart the app service, it works just fine again. I can browse it no problem.
