If you need coredump, that can be sent separatly.

Re: App crashes always writing config value to database
That's wired. Did you use a debug build of your app. And if not, may I ask to do so? Because in that case we should get some line numbers to figure out on which line in TaskWriteConfig source file the crash will happen. That will help allot.

Also I don't understand what the writeLastTokenRefreshAtTask does and where it comes from. That could help to understand the crash a bit better, too.

Regards,
Marc

Re: App crashes always writing config value to database
Hi Marc
I will try with debug build und let you know about results and the writeLastTokenRefreshAtTask is a simple ITask like:

std::unique_ptr<ITask> writeLastTokenRefreshAtTask;

in instance class Header:

class WhoisOn : public AppInstance , public AppUpdates , public UDatabase , public UWebserverPlugin , public JsonApiContext , public ConfigContext { ConfigString lastTokenRefreshAt; }

in instance class CPP:

WhoisOn::WhoisOn( IIoMux * const iomux , WhoisOnService * service , AppInstanceArgs * args ) : AppInstance(service, args) , AppUpdates(iomux) , ConfigContext(nullptr, this) , stopping() , pbxSession() , accessToken(this, "accessToken", "") , refreshToken(this, "refreshToken", "") , lastTokenRefreshAt(this, "lastTokenRefreshAt", "") }

that is started here as described in initial post:

else if (task == writeExpiresInTask.get())
{ if (isTeamsAccessTokenRefreshFailed == false)
{ writeLastTokenRefreshAtTask.reset( instance->WriteItemValue( &instance->lastTokenRefreshAt , getTimeStamp() , false ) );
writeLastTokenRefreshAtTask->Start(this); } else { TaskFailed(task);
}
}
else if (task == writeLastTokenRefreshAtTask.get())
{ instance->AccessTokenRefreshComplete(true);
}
