Azure web app domain license missing

Overview I am currently working on deploying an upgraded XbK project to our Azure hosted UAT environment. The project was upgraded from version 26 and is now at 27.0.1.

After deploying I get errors when trying to access the site. The errors point to a missing license for the azure app's domain however we previosuly did not need a license for the app domain since traffic went through the custom domain.

Is there something I am potentially overlooking?

Deployment steps When deploying I followed the following high level steps:

• Deployed published code to UAT environment.
• Targeted UAT environment from local and ran DB upgrade command.
• Ran CD command targeting UAT environment.

All steps were executed successfully. Afterward, I could access the admin, and I can see my site channel and all the content types in the tree.

Errors Although I can see the content in the tree, I cannot access each content items content or preview. If I click on a node I get an internal server error. See Eventlog point 1 for event log errors first few lines of stack trace.

If I try access the site using the assigned domain which worked pre-upgrade I get a 404 error. See Eventlog point 2 for event log errors first few lines of stack trace.
