Exhibit

// Widget server script
data.items = [];
var gr = new GlideRecord('incident');
gr.query();
while(gr.next()) {
    data.items.push(gr.getRow());
}

Refer to the exhibit. The developer expects a list of incidents in the widget, but the page renders with an error. What is the most likely cause?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

getRow() is not a valid method on GlideRecord

The error occurs because getRow() is not a valid method on GlideRecord. The correct method to access field values from a GlideRecord object is getValue(). Option A is not the most likely cause because server scripts do not require an explicit return statement; the data structure is implicitly returned. Option C is a logic issue, not a syntax error. Option D is incorrect because the data.items array is correctly initialized with new Array() or [] and then pushed in the loop.

✗
The query does not filter for active incidents
Why it's wrong here
Incorrect: This would not cause an error, just empty data.
