precondition failing for deployment of storage account

I am trying to deploy storage account which is getting deployed succesfully first time but when I try to re-deploy it ,it fails and complains about default blob deployment pre-condition failed for following section of the bicep template

resource blob_default 'Microsoft.Storage/storageAccounts/blobServices@2021-04-01' = {
    name: 'default'
    parent: stg
    properties: {
      changeFeed: {
        enabled: true
      }
      restorePolicy : {
        enabled: true
        days: 6
      }
      containerDeleteRetentionPolicy: {
        enabled: true
        days: 7
      }
      cors: {
        corsRules: []
      }
      deleteRetentionPolicy: {
        enabled: true
        days: 7        
      }
      isVersioningEnabled: true
    }
}

this child blob resource is part of storage account deployment template and it is failure cause in overall deployment of storage account with error message

{ "status": "Failed", "error": { "code": "ContainerOperationFailure", "message": "The condition specified using HTTP conditional header(s) is not met.\nRequestId:5d03a3d7-e01e-0052-65d4-a8f390000000\nTime:2021-09-13T19:20:18.8705109Z" } }
