I have an output in deployment/vpc that calls on the output in the module/vpc with the value as follow “value = module.vpc.vpc_id”. This works and display the output value. I’m trying to do the same in deployment/security-groups/outputs using the value “value = module.security-groups.security_group_arn” but when I plan in TFG I get “Error: Reference to undeclared module. │ No module call named “security-groups” is declared in the root module”. the reference to the module …/terraform-infra.git//modules/security-groups?ref=dev. This works when I plan without the output call the plan executes.
output.tf in security-groups module
output “security_group_arn” {
description = “The ARN of the security group”
value = values(aws_security_group.sg)[*].arn
}
output.tf in security-groups/deployment
“output “security_group_arn” {” {
description = “The ARN of the security group”
value = module.security-groups.security_group_arn
What do I do wrong?
