Error: Attribute redefined

I have this error

Error: Attribute refined

on terraform.tfvars line 5:
5: tags = {

The argument “tags” was already set at Terraform.tfvars:4,1-5. Each argument may set only once

But I don’t even have a Terraform.tfvars file?

But I do see in one of the shell scripts

cat “$TF_App_Vars” “$TF_Tags_Vars” > “$TF_Main_path/terraform.tfvars”
Win 10
0.12.9

What are these shell scripts?

What command do you type which leads to the error message?

Which files do you have in the folder?
