If you wish to run and or make modifications to the E2E testing you will need to create an appsettings.json with all the required settings. Use the standard format for values instead of the functions formatting.

{
  "AzureWebJobsStorage": "UseDevelopmentStorage=true",
  "AzureWebJobsDashboard": "UseDevelopmentStorage=true",
  "fqdn": "<FQDN>",
  "tentantid": "<Tentant ID>",
  "clientsecret": "<Client Secret>",
