Help Parsing a JSON String in ServiceNow Workflow Editor

[appstorm]

When trying to parse a JSON string from the course_information field on a requested item, the IF statement errors out on the workflow.

{"PTRM_CODE":"81X","SUBJ_CODE":"HIMT","CRSE_NUMB":"101","SEQ_NUMB":"10P"}

// Parse the JSON string in the course_information field
var courseInfo;
 
try {
    courseInfo = JSON.parse(current.course_information);
} catch (e) {
    // Handle parsing error (if needed)
    return false; // or log the error
}
 
// Check if PTRM_CODE is "81X"
if (courseInfo.PTRM_CODE === '81X') {
    return true;
} else {
    return false;
}

I'm guessing this is something to do with the JSON string, itself, because the course_information field is returning null or undefined.  Any help is appreciated!
