[Junaidfarook]

monitors = {
"CF-origin-latency" = {
name = "cloudfront origin latency"
query = {

    type = "metric_standard"
     
    params = {
     
      time_aggr   = "avg"
      time_window = "current_1mo" 
      metric   = "aws.cloudfront.origin_latency"
      tags     = "aws_account:1231,environment:staging,application:abc"
      operator = ">"
      key      = "name"
      function = "default_zero(aws.cloudfront.origin_latency{*})"
    }
  }
  
  #### upon running it says 400 Bad Request: {"errors":["The value provided for parameter 'query' is invalid"]}

Hello,
not 100% sure why it fails, but I prepared a small example of how to use default_zero as string:

To do more troubleshooting can I think can be used used approach from debugging page https://terragrunt.gruntwork.io/docs/features/debugging/
