💡 Hint

Common Mistakes

Using 200 means success, not error.

Using 500 means server error, not resource missing.

The HTTP status code 404 means the requested resource was not found.

Common Mistakes

Using numeric codes without quotes.

Using unquoted words causing syntax errors.

The error code should be a string like "UNAUTHORIZED" for machine consumption, not a number or variable.

4fill in blank

Fill both blanks to create a JSON error response with a code and a human message.

Rest API

💡 Hint

Common Mistakes

Swapping code and message values.

Using numeric codes as strings for messages.

The error code "FORBIDDEN" and message "Access denied" clearly communicate the error.

5fill in blank

hard

Fill all three blanks to return a JSON error with code, message, and a numeric HTTP status.

Rest API

💡 Hint

Common Mistakes

Using status as a string instead of number.

Mixing up code and message values.

The error code is "INVALID_INPUT", message is descriptive, and status is the numeric HTTP code 422.
