This SNOW-CSA practice question tests your understanding of reporting, sla and imports. 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.
An import set transform map includes field maps with script actions. The import fails with 'Script execution error'. Where should the administrator look first?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
Import set row errors
Why wrong: Row errors show the error message and row data; this is the primary place to look.
Data source configuration
Why wrong: Data source configuration is checked before import, not for script execution errors.
Transform map's field map log
Why wrong: There is no specific field map log; errors are captured in row errors.
System log
The system log is a good source but may be less specific than row errors.
Answer choices

Correct answer & explanation
System log
When a script action in a transform map field map throws an error, the system log (syslog) is the primary source for detailed JavaScript error messages, stack traces, and line numbers. Import set row errors only capture row-level failures like missing mandatory fields, not script execution details. The data source configuration and field map log do not store runtime script errors.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Import set row errors
Why it's wrong here
Row errors show the error message and row data; this is the primary place to look.
Data source configuration
Why it's wrong here
Data source configuration is checked before import, not for script execution errors.
Transform map's field map log
Why it's wrong here
There is no specific field map log; errors are captured in row errors.
System log
Why this is correct
The system log is a good source but may be less specific than row errors.
Clue confirmation
The clue word "first" in the question point toward this answer.

Common exam traps
The trap here is that candidates often confuse 'import set row errors' (which show row-level validation failures) with 'script execution errors' (which are JavaScript runtime errors logged only in the system log), leading them to incorrectly select option A.
Trap categories for this question
Command / output trap
Row errors show the error message and row data; this is the primary place to look.
Detailed technical explanation
Under the hood, when a transform script or field-level script action executes, the ServiceNow JavaScript engine writes any unhandled exceptions to the system log (syslog table) with a severity of 'Error' and a source of 'Transform'. The system log entry includes the exact script, line number, and error message, enabling precise debugging. In a real-world scenario, a script action that attempts to access a null glide_record field will throw a 'Cannot read property of null' error, which only appears in the system log, not in row error tables.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the SNOW-CSA 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.
