I have followed all the given limitations and instructions given in this MS Doc but I'm unable to deploy the flex consumption plan function app.

Requested features are not supported in region. Please try another region. (Code:)

Here What I'm doing is:

1. I'm trying to create the Azure Function App with Python 3.11 as Runtime stack in the flex consumption model of app service plan using BICEP template
2. That function app with no public network access and integrated with outbound subnet and its private endpoint can be created using inbound subnet.

Please ensure that you follow this for the plan creation:

resource flexFuncPlan 'Microsoft.Web/serverfarms@2024-04-01' = {
  name: planName
  location: location
  tags: tags
  kind: 'functionapp'
  sku: {
    tier: 'FlexConsumption'
    name: 'FC1'
  }
  properties: {
    reserved: true
  }
}
