ARM Template: Incorrect storage endpoint for AppSettings, WEBSITE_CONTENTSHARE

Getting error when deploying Azure function to USGov Arizona using ARM template. Template works in Azure commercial. Error is:

12:34:11 - 12:33:27 PM - Resource Microsoft.Web/sites/config 'SFGovAppService/appsettings' failed with message '{
12:34:11 -   "Code": "BadRequest",

12:34:11 -         "Parameters": [
12:34:11 -           "The remote name could not be resolved: 'sftestgovstorage.file.core.windows.net'"
12:34:11 -         ],
12:34:11 -         "Code": "BadRequest",
12:34:11 -         "Message": "There was a conflict. The remote name could not be resolved: 'sftestgovstorage.file.core.windows.net'"
12:34:11 -       }
12:34:11 -     }
12:34:11 -   ],
12:34:11 -   "Innererror": null
12:34:11 - }'

I have a successfully-deployed file service endpoint at https://sftestgovstorage.file.core.usgovcloudapi.net/, within the same resource group, same location (USGov Arizona).

Based on testing, I know that the error is being caused by the "WEBSITE_CONTENTSHARE" property in the template: ("~" = code that I've removed to shorten this.)

},

I do know that AppSetting deployment works because I have been able to deploy this configuration to the government tenant using a PUT REST call (via Fiddler)

The issue/question: To me, the template deployment process in this government tenant appears to be looking for a commercial endpoint (file.core.windows.net). Is there a way I can override/correct this?

WEBSITE_CONTENTAZUREFILECONNECTIONSTRING and WEBSITE_CONTENTSHARE should only be used for Function Apps running in Consumption mode, and Azure Government currently doesn't support Consumption.

Try simply omitting both these settings altogether.
