Error: no matching member function for call to 'AddRaw'

[adarshjamuaar]

Hi,
The plugin works fine during development but when I try to build it for my Quest 3, I get two errors.

1. Issue related to AddRaw

/Plugins/ROSIntegration-master/Source/ROSIntegration/Private/rosbridge2cpp/WebsocketConnection.cpp(64,28): error: no matching member function for call to 'AddRaw'
WebSocket->OnRawMessage().AddRaw(this, &WebsocketConnection::OnRawMessage);
~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~

2. Issue related to Exception handling

Plugins/ROSIntegration-master/Source/ROSIntegration/Private/rosbridge2cpp/WebsocketConnection.cpp(110,2): error: cannot use 'try' with exceptions disabled
try {
^

I have succeeded in removing all other errors but I am stuck with these two now. Please help me to resolve this.
I am using UE 5.0.3

Hi @adarshjamuaar ,

I recently made a PR that should address your second issue (with the try-catch block).

Regarding the first problem with the AddRaw method, there are actually 4 lines, 61-64, that all invoke that method. Is it just line 64 that causes the problem or do all of them throw the same error? UE5 still uses delegates, so I'm kind of confused as to what is causing the problem.
