Version 3.7.4 Compilation Errors, AsyncWebSocket and AsyncWebHeader, updating code from V2.x.x

[NinoBenci]

Firstly, I'm new to V3.7.4, as I have been using V2.x.x with some old (pre 2022) code.
I have searched through similar discussion but have been unable to find a suitable resolution that clearly details the error.
I am not fully conversant with Async Web Server components or Web programming and rely on more knowledgeable coders.
Attempting to update old code (including updating the code to ArduinoJson V7.x.x) to the latest iteration and am now stuck at a point where these are the only two bugs left.

error: invalid conversion from 'const AsyncWebHeader*' to 'AsyncWebHeader*' [-fpermissive]
  217 |     AsyncWebHeader *header = request->getHeader("Host");
      |                              ~~~~~~~~~~~~~~~~~~^~~~~~~~
      |                                                |
      |                                                const AsyncWebHeader*

and

error: cannot convert 'AsyncWebSocketClient' to 'AsyncWebSocketClient*' in initialization
  708 |          ((AsyncWebSocket *)this->ws)->getClients()) {

Notes or pointers that can help me understand better would be very much appreciated.
I can post the full code source if required.

Thankyou in advance

some methods has been changed since 2.x for various reasons, you need to update your code.
i.e. add const qualifier here

const AsyncWebHeader *header = request->getHeader("Host");

it means you can't change header's data in request.

The second is misuse of a pointer notation, maybe you need yo use a . instead of ->?

Thank you for the reply and information.
The original V2.x.x code was not written by myself and the original author has not maintained it. It has been a very steep learning curve for me.
