UNSOLVED GetGeneralLicensingInformation() in TeamRender Client fails


The very beginning of my plugin's PluginStart() looks like this:

Bool PluginStart()
		GePrint("Activation aborted!"_s);
		return false;

	// License validation check
	maxon::String productId, systemId, userId, licenseId, userName;
	GetGeneralLicensingInformation(productId, systemId, userId, licenseId, userName) iferr_return;

	// ...
	// a lot more code that checks for plugin license and registers the plugins...
	// in TR Client, it is never executed, because GetGeneralLicensingInformation() throws an error.
	// ...

	return true;

Running it in Cinema 4D or TeamRender Server works fine, but in TeamRender Client, the call to GetGeneralLicensingInformation() returns an error and jumps to the error handler. Why?

Should I simply check if GeGetVersionType() returns VERSIONTYPE::TEAMRENDER_CLIENT and then skip the call? If so, it would be nice if that was mentioned in the SDK docs.

Environment is:

  • R21.026
  • Xcode 10.1
  • macOS 10.13.6


Well, what error does GetGeneralLicensingInformation() return? You can check the error message: Error Class

The way it's described in the SDK docs, I do not get any error message:

By diving into the location in the API where the error is thrown, I might have found that it's a nullptr error.
