AI Summary: The Go code in the Track-It project is encountering an error when unmarshalling JSON data. The `Problem_ID` field in the `Problem` struct is of type `int`, but the JSON input is providing a string value. The task is to fix this type mismatch, likely by changing the `Problem_ID` field type to `string` or converting the string input to an integer before unmarshalling.
