Terraform: working with 'InvalidArgumentException' When Creating RDS Instances with Parameter Groups
I've been researching this but I'm writing unit tests and I'm trying to configure I'm writing unit tests and Could someone explain I'm trying to create multiple Amazon RDS instances using Terraform, and I'm working with an `InvalidArgumentException` related to the parameter groups... I've defined a parameter group and then attempted to associate it with my RDS instances, but Terraform keeps throwing this behavior: ``` behavior: InvalidParameterValue: The specified parameter group 'my-custom-parameter-group' is not associated with the specified DB engine and version. ``` Here is the relevant part of my Terraform configuration: ```hcl resource "aws_db_parameter_group" "my_parameter_group" { name = "my-custom-parameter-group" family = "mysql8.0" description = "Custom parameter group for MySQL 8.0" parameter { name = "max_connections" value = "200" } } resource "aws_db_instance" "my_db_instance" { count = 2 identifier = "mydbinstance-${count.index}" engine = "mysql" engine_version = "8.0.25" instance_class = "db.t3.micro" allocated_storage = 20 parameter_group_name = aws_db_parameter_group.my_parameter_group.name db_subnet_group_name = aws_db_subnet_group.my_subnet_group.name vpc_security_group_ids = [aws_security_group.my_security_group.id] } ``` I have ensured that the DB engine and version specified for the parameter group match with the RDS instances' configuration, yet the behavior continues. I've also checked the AWS console and confirmed that the parameter group is correctly associated with the MySQL 8.0 version. I've tried running `terraform apply` multiple times, and I've even destroyed the previous resources before reapplying. Could this scenario be stemming from the timing of resource creation or some other subtle configuration detail? Any suggestions for troubleshooting or resolving this scenario would be greatly appreciated! Any feedback is welcome! I'm working in a Debian environment. Is there a simpler solution I'm overlooking? I'm using Hcl 3.9 in this project.
