Validating the configuration attributes is included within the messages component and the accompanying console warnings or errors. The configuration attributes have distinct validation checks for input formatting and values to ensure validity. See the reference tables for a full list of accepted options.

If the validation fails, the web browser's developer console displays warning messages that inform you which property is invalid and what you need to do to address the issue. In general, the library attempts to fall back to the safe default values if there are missing or invalid inputs.
