NB2KG fails when notebook is configured with different base_url #18

Closed lresende closed 6 years ago

lresende commented 6 years ago

Steps to reproduce:

Error on console:

Uncaught exception GET /jupyter/notebook/api/kernelspecs (::1)
    HTTPServerRequest(protocol='http', host='localhost:8888', method='GET', uri='/jupyter/notebook/api/kernelspecs', version='HTTP/1.1', remote_ip='::1')
    Traceback (most recent call last):
      File "/Users/lresende/opt/anaconda3/lib/python3.6/site-packages/tornado/web.py", line 1592, in _execute
        result = yield result
      File "/Users/lresende/opt/anaconda3/lib/python3.6/site-packages/tornado/gen.py", line 1133, in run
        value = future.result()
      File "/Users/lresende/opt/anaconda3/lib/python3.6/site-packages/tornado/gen.py", line 326, in wrapper
        yielded = next(result)
      File "/Users/lresende/opensource/jupyter/nb2kg/nb2kg/handlers.py", line 324, in get
        kernel_specs = yield gen.maybe_future(ksm.list_kernel_specs())
    AttributeError: 'CondaKernelSpecManager' object has no attribute 'list_kernel_specs'

Note in the exception Uncaught exception GET /jupyter/notebook/api/kernelspecs that the base gateway url is being created using the notebook base url which is invalid on the gateway side.

Invalid, the issue was around proper registration of NB2KG on the environment I was seeing this.
