Azure Functions App yields errors after setting App Settings

Question

I have an Azure Functions App running on a consumption plan. It was handed over to me without any app settings. I manually setup the app settings using the Microsoft documentation as follows:

  {
    "name": "APPINSIGHTS_INSTRUMENTATIONKEY",
    "value": "{id}",
    "slotSetting": false
  },
  {
    "name": "AzureWebJobsStorage",
    "value": "DefaultEndpointsProtocol=https;AccountName={name};AccountKey={key}",
    "slotSetting": false
  },
  {
    "name": "FUNCTIONS_EXTENSION_VERSION",
    "value": "~2",
    "slotSetting": false
  },
  {
    "name": "FUNCTIONS_WORKER_RUNTIME",
    "value": "dotnet",
    "slotSetting": false
  },
  {
    "name": "WEBSITE_CONTENTAZUREFILECONNECTIONSTRING",
    "value": "DefaultEndpointsProtocol=https;AccountName={name};AccountKey={key}",
    "slotSetting": false
  },
  {
    "name": "WEBSITE_CONTENTSHARE",
    "value": "{name of Functions App added to 32 chars}",
    "slotSetting": false
  },
  {
    "name": "WEBSITE_NODE_DEFAULT_VERSION",
    "value": "10.14.1",
    "slotSetting": false
  },
  {
    "name": "WEBSITE_RUN_FROM_PACKAGE",
    "value": "1",
    "slotSetting": false
  }
]

Where the connection strings both share the same Storage Account that is otherwise empty and not in use by any other application.

It however yields an error already when trying to view it from the portal. Removing the WEBSITE_CONTENTAZUREFILECONNECTIONSTRING, WEBSITE_CONTENTSHARE and AzureWebJobsStorage seem to make it run although no host keys are saved, but otherwise functions seem to trigger.

How do I properly setup the Functions App to use the Storage?

create a new empty function app and see which settings are created. ensure that your azurewebjobstorage is pointing to a storage account — Alex Gordon
@l--''''''---------'''''''''''' Creating a new function did the trick. It removed the FUNCTIONS_WORKER_RUNTIME and set the WEBSITE_NODE_DEFAULT_VERSION to 8.11.1. Everything seems to work as intended now. You can add it as anwser — 404

By creating a new function app and comparing the settings that are created to your current settings, you will be able to identify the differences.
