Unable to Creating a GCP alert with 2 or more conditions with nested maps

Hello there I’m trying to create an GCP alert using more than 1 condition using a nested map(object) variable.
here is my variable:
new_alert = {

  alert01 = {

     alert_displayname = "terraform-hdfs_datanodes_down"

     combiner_var = "OR"

     notification_channels_var = [

        "projects/mckesson-test-env/notificationChannels/18428528452968721018",

        "projects/mckesson-test-env/notificationChannels/17359140270922751940"

     ]

     user_labels_var = "bar"       

     project_id = "mckesson-test-env" 

     all_conditions = {

        condition01 = {

           condition_displayname= "terraform-test-condition 2"

           filter_alert="metric.type=\"dataproc.googleapis.com/cluster/hdfs/datanodes\" resource.type=\"cloud_dataproc_cluster\" metric.label.\"status\"=\"running\""    

           comparison_var="COMPARISON_LT"

           threshold_value_var=2

           duration_var="60s"

           aligment_period_var="60s"

           per_series_aligner_var="ALIGN_MEAN"

        },

        condition02 = {

           condition_displayname= "terraform-test-condition 3"

           filter_alert="metric.type=\"router.googleapis.com/nat/allocated_ports\" resource.type=\"nat_gateway\""

           comparison_var="COMPARISON_GT"

           threshold_value_var=4

           duration_var="120s"

           aligment_period_var="120s"

           per_series_aligner_var="ALIGN_MEAN"

        },

     }   

  },

}

and here is my main code:

resource “google_monitoring_alert_policy” “new_alert” {

for_each = var.new_alert

display_name = each.value[“alert_displayname”] #alert policy name

combiner = each.value[“combiner_var”]

notification_channels = [

 for noti in each.value ["notification_channels_var"] :

 noti

]

project = each.value[“project_id”]

conditions {

 for key, value in each.value : [  #getting an error here

    display_name = each.value["condition_displayname"]   #Metric name

    condition_threshold {      

       filter     = each.value["filter_alert"]      

       comparison = each.value["comparison_var"] #Configuration>Condition triggers if>any time series violates> is above

       threshold_value = each.value["threshold_value_var"]

       duration   = each.value["duration_var"]

       aggregations {

          alignment_period   = each.value["aligment_period_var"]

          per_series_aligner = each.value["per_series_aligner_var"]

       }

    }

  ]

}

user_labels = {

foo = each.value["user_labels_var"]

}

}

I’m getting error in this loop
for key, value in each.value : [ #getting an error here

anyone knows how to do a loop in a nested map of objects?
