Updating Azure firewall failed

Question

I am trying to add a rule to the azure firewall policy rule collection, but the pipeline is failing with the error
The code is written in Terraform with version 1.2.7 and AzureRm with version 2.98.

waiting Firewall Policy Rule Collection Group "AzureTestRule" (Resource Group "xxxx-xxx-xxx-rg" / Policy: "xx-policy"): Code="FirewallPolicyUpdateFailed" Message="Put on Firewall Policy xx-policy Failed with 1 faulted referenced firewalls"

I have 8 rule collections each with app rules and net rules

collection1{
app-rule1{
rule1{
}
rule2{
}
......
rule_n{
}
}
net-rule1{
rule1{
}
rule2{
}
......
rule_n{
}
}
}
....
collection8 {}

Can anyone provide me a solution to fix it
