Flex Consumption pricing tier is not enabled for this subscription

Question

HI Microsoft Azure Team,

Greetings for the day and Wish you a happy new year.

I'm deploying the Azure Function App in Flex Consumption Model. Using the Portal, I'm able to deploy it successfully but using the bicep code deployment, getting an error as shown below:

Error:

New-AzResourceGroupDeployment: 9:41:52 PM - The deployment 'FlexFuncAppDeployment' failed with error(s). Showing 1 out of 1 error(s).
Status Message: Flex Consumption pricing tier is not enabled for this subscription. (Code: BadRequest)
 - Flex Consumption pricing tier is not enabled for this subscription. (Code:)
 -  (Code:BadRequest)
 -  (Code:)

Bicep Code:

  name: 'vvkstaccforflexfuncapp'

          authentication: {
            type: 'SystemAssignedIdentity'
          }
          
        }
      }

    virtualNetworkSubnetId: '/subscriptions/<azure-subscription-id>/resourceGroups/vivekchak-rg/providers/Microsoft.Network/virtualNetworks/vnetforflexfuncapp/subnets/OutboundSubnet'    
  }
}

Following this MS Documentation, I have done the below things:

1. Removed deprecated properties and used the required only.
2. Creating the Function App with public network access disabled and enabling the virtual network integration.

Could you please assist me.

Thanks in Advance.

@Rajoli Hari Krishna Thanks for posting your question in Microsoft Q&A, apologize for any inconvenience caused on this.

I understand that you are unable to deploy flex-consumption function app from the portal in West US region.

Currently below are the regions which are supported to deploy flex consumption function apps.

northeurope,southeastasia,eastasia,eastus2,southcentralus,australiaeast,eastus,northcentralus(stage),westus2,uksouth,eastus2euap,westus3,swedencentral

Here is the Azure CLI command to check which regions support Flex consumption function apps.

az functionapp list-flexconsumption-locations --output table

I would suggest you try deploying to above suggested regions.

Hope this helps, let me know if you have any further questions on this.
