Fragment shader seems to fail to compile but the problematic fragment shader code is not mine

The Qt opengl\cube example project works but it is output'ing the following message to DbgView:

[1996] QOpenGLShader::compile(Fragment): ERROR: 4:1: 'textureSampler' : syntax error syntax error

I am using Qt 5.15.8. The platform is Windows 7.

The computer is supposed to support OpenGL4.4:

Hi,

Which version of Qt are you using ?
Do you have the same issue if you run Qt's OpenGL examples ?
