💡 Hint

Common Mistakes

Using the wrong function name to check user existence.

Using incorrect JSON keys or messages.

Not returning status 409 for conflict.

The function checks if the user exists using user_exists. If yes, it returns a JSON with key "error" and message "User already exists" with status 409.
