[Kihan15]

Hello,

I have the follwing error when I try to use definition module. any idea?
thanks,

│ Error: Error in function call
│
│ on ../../modules/definition/variables.tf line 110, in locals:
│ 110: policy_rule = coalesce(var.policy_rule, try((local.policy_object).properties.policy_Rule, null))
│ ├────────────────
│ │ while calling coalesce(vals...)
│ │ local.policy_object is object with 3 attributes
│ │ var.policy_rule is null
│
│ Call to function "coalesce" failed: no non-null, non-empty-string arguments.

main.tf:

##################

Monitoring

##################

create definitions by looping around all files found under the Monitoring category folder

module "deploy_resource_diagnostic_setting" {
source = "../../modules/definition"
for_each = toset([
for p in fileset(path.module, "../../policies/Monitoring/*.json") :
trimsuffix(basename(p), ".json")
])
policy_name = each.key
policy_category = "Monitoring"

}

I found the issue:

I changed the variables.tf under the module/definition:
line 110:
from: policy_rule = coalesce(var.policy_rule, try((local.policy_object).properties.policy_Rule, null))
to: policy_rule = coalesce(var.policy_rule, try((local.policy_object).properties.policy_Rule, {} ))

thank you,
