When debugging an FME workspace, which practice is recommended regarding parameters?

• A. Ignore parameter values
• B. Check reader, writer, or transformer parameters at the point of failure
• C. Only check the parameters at the start
• D. Rely on defaults without verification

Answer: (B)

Verifying the parameter values of the component that reports the failure is essential when debugging an FME workspace. The error message usually points to a specific reader, writer, or transformer, and those parameters determine how that piece of the workflow behaves—what file or database it uses, how data is interpreted, and where outputs go. By inspecting the parameters at the moment the failure occurs, you confirm whether the configuration matches what the workflow expects and quickly spot issues like an incorrect path, a mismatched data type, or a missing resource. Parameters can be driven by workspace variables or data-driven logic, so the values in use during execution are the ones that matter, not what you saw at the start. Relying on defaults or checking only upfront can miss problems that only appear under actual run conditions.
