Sbsrender no output gpu linux

[emilche]

Hello. So I am trying to create a docker container that utilizes the gpu.
But when it goes through the sbsrender with the engine set to ogl3 it does not generate an output.
It seems to boot up but that is about it.
Here is the report it gives me:

[INFO][SBSRender]Will load engine located at "/opt/Allegorithmic/Substance_Designer/plugins/engines/libsubstance_ogl3_blend.so.1".
[INFO][SBSRender]Results from graph "pkg://XXXX" into package "/usr/local/lib/python3.9/dist-packages/XXXX/dem_height_upscaler.sbsar" :
[
{
"identifier": "XXXX",
"outputs": [
]
}
]

and here is what it looks like when using the cpu version:

[INFO][SBSRender]Will load engine located at "/opt/Allegorithmic/Substance_Designer/plugins/engines/libsubstance_sse2_blend.so.1".
[INFO][SBSRender]Results from graph "pkg://XXXX" into package "/usr/local/lib/python3.8/dist-packages/XXXX/dem_height_upscaler.sbsar" :

        "outputs": [
            {
                "identifier": "dem",
                "label": "dem",
                "type": "image",
                "uid": 2910303658,

                "value": "/tmp/tmpuhwr8ogx/dem_1_1_dem.png"
            }
        ]
    }
]

Any tips on why this is happening?
