Issue in converting Terraform into Intermediate Representation

[Tianyi2]

Describe the bug
When attempting to convert a Terraform file into GLITCH's intermediate representation using the --mode repr option, the tool encounters an error: AttributeError: 'Attribute' object has no attribute 'column'. This error prevents the successful generation of the intermediate representation.

To Reproduce
The command I use: glitch --tech terraform --mode repr /Personal' ' Storage/Project/research/glitch/playground/boolean_value_assign. Note that I create a playground folder in the glitch project.

Steps to reproduce the behavior:

1. Have a Terraform file named boolean_value_assign.tf located at /playground/boolean_value_assign.tf. I get the file from https://github.com/sr-lab/GLITCH/blob/main/glitch/tests/parser/terraform/files/boolean_value_assign.tf
2. Execute the following command in the terminal:
3. glitch --tech terraform --mode repr /Personal' 'Storage/Project/research/glitch/playground/boolean_value_assign.tf
4. Observe the AttributeError: 'Attribute' object has no attribute 'column' traceback.

Expected behavior
I expected GLITCH to successfully parse the Terraform file and generate its intermediate representation without any errors. The command should complete, and the representation should be outputted (or saved to a file, depending on GLITCH's default behavior for this mode).

Screenshots

Desktop (please complete the following information):

• OS: [Windows 11]
• Python: 3.11
• Download GLITCH with poetry install

Additional Context
When I test with another terraform file "backend.tf" with the following content the above issue does not occur, but generate an "empty IR".
The content in backend.tf

backend "s3" {
bucket = "s3bucketName" // s3 bucket name created from AWS console
key = "terraform.tfstate" // terraform state file
region = "" // provide s3 bucket region
}
}

The output

(.venv1) PS D:\Personal Storage\Project\research\glitch> glitch --tech terraform --mode repr /Personal' 'Storage/Project/research/glitch/playground/backend.tf
