Getting error when creating inference session *Browser*

Running into an error when trying to create an Inference session. Using React and onnx runtime web. I am using a custom model I ported over from PyTorch.

error below

TypeError: Cannot read properties of null (reading 'irVersion')
    at t.loadFromOrtFormat (ort-web.min.js:6)
    at t.load (ort-web.min.js:6)
    at ort-web.min.js:6
    at t.event (ort-web.min.js:6)
    at t.initialize (ort-web.min.js:6)
    at t.<anonymous> (ort-web.min.js:6)
    at ort-web.min.js:6
    at Object.next (ort-web.min.js:6)
    at a (ort-web.min.js:6)

Here is how I am creating an array buffer from model

        const created = async () => {
            // fetch the model file to be used later
            try {
              const response = await fetch(onyxModelFilepath);
              const modelFile = await response.arrayBuffer();
              setModelFile(modelFile);
            } catch (e) {
              console.log(e);
              setModelLoadingError(true);
            }
          };

and then creating a session from the said model which is where I am receiving the error

            export async function createModel(model) {
              try {
                return await InferenceSession.create(model);
              } catch (e) {
                console.error(e);
              }
            }

How I converted my PyTorch model

            net.eval()
            input_names = ["input"]
            # output names
            output_names = ["output"]
        
            # dummy input data 
            dummy_input = torch.randn(1, 3, 256, 256)
            
            torch.onnx.export(
                net.to(self.device), 
                dummy_input, 
                './classic_sr_gan.onnx', 
                input_names=input_names, 
                output_names=output_names,
                opset_version=11
            )
