The answer is that the JSON contains a trailing comma after the 'operator' line, which is invalid JSON syntax. This trailing comma causes the ServiceNow dashboard parser to fail when reading the filter configuration, resulting in the 'Invalid filter condition' error because JSON strictly prohibits commas after the last key-value pair in an object or array. On the ServiceNow Certified Application Developer CAD exam, this tests your understanding of how dashboards parse filter conditions and the importance of strict JSON formatting, often appearing as a subtle trap where a single extra comma breaks the entire filter. A common memory tip is to think of JSON as a strict list: no item gets a comma after it if it is the last one, so always double-check the final line of any JSON object for a rogue trailing comma.
SNOW-CAD Designing interfaces and user experiences Practice Question
This SNOW-CAD practice question tests your understanding of designing interfaces and user experiences. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Refer to the exhibit. A dashboard filter configuration contains the above JSON. When the dashboard runs, it shows an 'Invalid filter condition' error. What is the issue?

✗
The assignment group name is misspelled.
Why it's wrong here
Misspelling would cause no data, not an invalid filter error.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the SNOW-CAD exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
