thank you .. needs an update in GLBuffers...

Nope, you are using the wrong format, i.e.
https://registry.khronos.org/OpenGL-Refpages/gl4/html/glTexImage2D.xhtml
https://registry.khronos.org/OpenGL-Refpages/es3/html/glTexImage2D.xhtml

format

    Specifies the format of the pixel data. The following symbolic values are accepted: GL_RED, GL_RG, GL_RGB, GL_BGR, GL_RGBA, GL_BGRA, GL_RED_INTEGER, GL_RG_INTEGER, GL_RGB_INTEGER, GL_BGR_INTEGER, GL_RGBA_INTEGER, GL_BGRA_INTEGER, GL_STENCIL_INDEX, GL_DEPTH_COMPONENT, GL_DEPTH_STENCIL.

and in your code you pass the internal format as the 7th argument format.

The latter gets used to

Buffers.rangeCheckBytes(pixels, imageSizeInBytes(format,  type, width, height, 1  , false));

inside our glTexImage2D(..) function before passing along to OpenGL.

Hope it helps.
