Terraform how to to reference outputs from a module in another module with inconsistent variable types
I'm working with an scenario where I'm trying to pass output values from one Terraform module to another, but I'm running into problems with type mismatches... I have module A that outputs a string variable, and I want to pass that output to module B. However, module B is expecting a list type for that variable.\n\nHere’s a snippet of my module A where I define the output:\n```hcl\noutput "my_output" {\n value = "some-string-value"\n}\n```\nIn module B, I define the variable like this:\n```hcl\nvariable "input_from_module_a" {\n type = list(string)\n}\n```\nAnd I try to reference it in my main Terraform file like this:\n```hcl\nmodule "module_a" {\n source = "./module_a"\n}\n\nmodule "module_b" {\n source = "./module_b"\n input_from_module_a = [module.module_a.my_output]\n}\n```\nWhen I run `terraform apply`, I get the following behavior message:\n````plaintext\nError: Incorrect attribute value type\n\n on main.tf line XX:\n input_from_module_a = [module.module_a.my_output]\n\nInappropriate value for attribute "input_from_module_a": string required.\n```\nI’ve tried wrapping the output in `tolist()` and `flatten()`, but it still results in the same behavior. I’m not sure how to convert the single string output to a format that module B can accept. Any suggestions on how to handle this type inconsistency effectively? I'm using Terraform version 1.2.0. Thanks in advance for any help! Thanks in advance!
