gst_gl_context_fill_info glGetString error: 0x502

[Lusine Hayrapetyan]

Hi Folks,

I'm getting the following error from gst_gl_context_fill_info function:
* " glGetString error: 0x502"*

This is my code:
 state->x_gst_display =
gst_gl_display_x11_new_with_display(state->xdisplay);
 gst_gl_display_filter_gl_api(GST_GL_DISPLAY(state->x_gst_display),
GST_GL_API_GLES2);

 state->gl_context =
        gst_gl_context_new_wrapped(GST_GL_DISPLAY(state->x_gst_display),
        (guintptr)state->context, GST_GL_PLATFORM_EGL, GST_GL_API_GLES2);

    if ( !gst_gl_display_add_context(GST_GL_DISPLAY(state->x_gst_display),
state->gl_context))
        g_print("Failed to add gl_context to display\n");

    if (!gst_gl_context_activate(state->gl_context, TRUE))
        g_print("gst_gl_context_activate failed!");

    if (!gst_gl_context_fill_info(state->gl_context, &error)) // This line
produces the error
    {
        g_printerr ("Error received from gst_gl_context_fill_info %s\n",
error->message);
        return -1;
    }

Here is the output of gl*:7
