A developer needs to debug an issue where a client script is not triggering when a field changes. What is the most efficient first step in troubleshooting within Studio?

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

✓

Open the client script in Studio and use the 'Debug' button.

Studio includes a debug feature for client scripts that allows step-by-step execution and inspection. Option A is indirect, C is not relevant to client script execution, and D is server-side.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✗

    Review the syslog for error messages.

    Why it's wrong here

    While helpful, this is not the most efficient first step; Studio's debugger is more direct.

  • ✓

    Open the client script in Studio and use the 'Debug' button.

    Why this is correct

    This allows running the script in debug mode to see if it fires and track variables.

  • ✗

    Check the ACLs on the table.

    Why it's wrong here

    ACLs do not affect client script execution.

  • ✗

    Add a gs.log() statement to the server-side code.

    Why it's wrong here

    Client scripts run client-side; server-side logging won't help.
