As an AI language model, I cannot see the entire code that you are referring to. However, based on the error message you provided, it seems like there is a class called “AuthRequestHandler” which is inheriting from “HTTPRequestHandler”, but the definition of “HTTPRequestHandler” is incomplete. This error can occur if “HTTPRequestHandler” is forward-declared but not fully defined.
To fix this error, make sure that the definition of “HTTPRequestHandler” is complete and included in the header file or source file where “AuthRequestHandler” is defined. Alternatively, you could include the header file that defines “HTTPRequestHandler” before defining “AuthRequestHandler”.
