qmlplugindump error when building with MinGW 64bits (Qt 5.13.1)

I built an extension plugin in release mode with MinGW 32bits (Qt 5.13.1). When I run qmlplugindump everything works as expected and my .qmltypes file is well generated.

But when I build my plugin in release mode with MinGW 64bits (Qt 5.13.1) the qmlplugindump leads to the following error:

17:10:24: Starting: "C:\Qt\QtFramework\5.13.1\mingw73_64\bin\qmlplugindump.exe" -nonrelocatable NXSharedControllers 1.0 ...\NXSharedControllers > NXSharedControllers\nxsharedcontrollers.qmltypes

Does it mean anything to someone ?

I have found the cause of this issue. A dependency file was missing from the plugin build folder. I created a custom target with QMake in order to copy the dependency file to this folder.
