When trying to enable the capability "EnableUniqueIndexReIndex", it always give the error message "Invalid capability EnableUniqueIndexReIndex"

When I try to enable the capability "EnableUniqueIndexReIndex", I always get the error message "Invalid capability EnableUniqueIndexReIndex".

I tried with the az cli and with the bicep script that deploys the application. I have installed the cosmosdb az extension in the preview version.

$ az extension add --name cosmosdb-preview --allow-preview true
Extension 'cosmosdb-preview' 1.0.1 is already installed.

$ az cosmosdb update --resource-group <rg> --name <dbacc> --capabilities EnableMongo EnableServerless EnableUniqueIndexReIndex
The behavior of this command has been altered by the following extension: cosmosdb-preview (BadRequest) Invalid capability EnableUniqueIndexReIndex. ActivityId: <id>, Microsoft.Azure.Documents.Common/2.14.0 Code: BadRequest Message: Invalid capability EnableUniqueIndexReIndex. ActivityId: <id>, Microsoft.Azure.Documents.Common/2.14.0

When deploying with the bicep code:

resource dbacc 'Microsoft.DocumentDB/databaseAccounts@2024-05-15' = {
  name: parNomeDBACC
  location: parLocal
  kind: 'MongoDB'
  properties: {
    consistencyPolicy: {
      defaultConsistencyLevel: 'Eventual'
    }
    locations: [
      {
        locationName: parLocal
        failoverPriority: 0
        isZoneRedundant: false
      }
    ]
    databaseAccountOfferType: 'Standard'
    apiProperties: {
      serverVersion: '4.2'
    }
    capabilities: [
      {
        name: 'EnableServerless'
      }
      {
        name: 'EnableUniqueIndexReIndex'
      }
    ]
  }
  tags: {
    componente: 'database'
    regiao: parLocal
    projeto: parNomeProjeto
  }
}

It gives as the result:

{"status":"Failed","error":{"code":"DeploymentFailed","target":"/subscriptions/<id>/providers/Microsoft.Resources/deployments/criaDev","message":"At least one resource deployment operation failed.
