Cloud Nat Module always changed value to default when tcp_established_idle_timeout_sec was set as number

Hi ✋
Hire is Cloud Nat Module's property I'm mentioning

• tcp_established_idle_timeout_sec
• icmp_idle_timeout_sec
• min_ports_per_vm
• tcp_transitory_idle_timeout_sec
• udp_idle_timeout_sec

these properties has string type but value is number .
It confused me.
And we can run plan and apply if the properties were set as number like

variable "nat" {
     name                               = string
     nat_ip_allocate_option             = string
     source_subnetwork_ip_ranges_to_nat = string
-    icmp_idle_timeout_sec              = number
-    min_ports_per_vm                   = number
     tcp_established_idle_timeout_sec   = string
-    tcp_transitory_idle_timeout_sec    = number
-    udp_idle_timeout_sec               = number

especially, tcp_established_idle_timeout_sec is back to default value 1200 when I set any timeout count like 60 as number.

Requests

I suggest that the properties can be also set as number or when users set as number and run terraform plan , generate an error.

Thanks for reading.
