TSLab version 1.0.21 not working properly with AllTheKernels kernel version 1.2.0

[paolocarinci]

Whenever you execute a command in AllTheKernels kernel (either in a notebook or in a shell), e.g.

>jslab
console.log("Test");

the cell remains running indefinitley and no output is shown.
In the logs I spotted an error message that says that a JSON parse exception has occurred.

[AllTheKernelsApp] Relaying execute_request to jslab
UnhandledPromiseRejection: SyntaxError: Unexpected token 'a', "a07332d4ce"... is not valid JSON
    at JSON.parse (<anonymous>)

    at /opt/jupyterhub/lib/node_modules/tslab/dist/jupyter.js:435:30

while the AllTheKernels kernel works fine with all the other kernels I use (IPython, Gophernotes, Bash, C, IJava).

Thanks for the message, this is a bug in tslab, as you've already reported. Should be fixed by yunabe/tslab#99
