Not sure if you can provide some pointers here. I'm using this with the Jupyter Kernel Gateway and it's the only shell that doesn't seem to work when running the gateway in HTTP mode. It works fine in web socket mode.

Hi I'm following the docs here: https://jupyter-kernel-gateway.readthedocs.io/en/latest/http-mode.html

It doesn't seem to mention how to select a different kernel when running in http mode. I was assuming it would take the kernel type from the .ipynb file that is used to provide the mappings for the http endpoints. Am I missing something here ?

I can see I have 2 kernels installed e.g.

Available kernelspecs: {
  default: 'python3',
  kernelspecs: {
    python3: { name: 'python3', spec: [Object], resources: [Object] },
    bash: { name: 'bash', spec: [Object], resources: {} }
  }
}

The bash kernel is working perfectly running in Web Socket mode. However, its doesn't seem to work in http-mode.

I just saw that there was an option to force the kernel during startup. e.g. --KernelGatewayApp.force_kernel_name=bash however this does not appear to have any affect on the error.

A little more info:

I have a cell in a notebook file:

# GET /hello/bash
echo "fsdfdsadsds"

it gets registered perfectly:

The error corresponds to my curl command that looks like this:

curl http://127.0.0.1:5006/hello/bash
Error : 127 

Just for clarity, here's a complete log - Looks like the "bash' kernel is being instantiated properly:
