Was unable to find the source_path "null" using the aws lambda module in terraform?

edit

This error message usually indicates that the source code directory or file specified for Lambda function deployment is either missing or not accessible. To resolve this error, ensure that you have provided the correct source_path parameter in your Terraform configuration and that it refers to a valid location containing the Lambda function code. Also, ensure that the code is readable by the IAM role or account used by Terraform to deploy the function.
