This error is a Java exception that occurs when trying to parse a string into a numeric value, but the string is empty or contains non-numeric characters.

In this particular case, the error occurred in the Swagger framework while trying to generate an example value for a parameter. The parameter is likely defined as a numeric type (such as long), but no default value or example was provided, so Swagger attempted to generate one based on the parameter type. However, either the value generated was empty or it contained non-numeric characters, leading to the NumberFormatException.

To fix this error, you need to ensure that the parameter has a valid default value or example value defined. If the parameter is optional, you can set a default value that will be used if no value is provided. If the parameter is required, you should provide an example value that is valid for the parameter type
