Extension is not working for JupyterLab version 2.0.0

[farhan5900]

I have following setup:
jupyter --version:

  jupyter-notebook : 6.0.3
  qtconsole       : not installed
  ipython           : 7.13.0
  ipykernel        : 5.2.0
  jupyter client  : 6.1.2
  jupyter lab      : 2.0.0
  nbconvert       : 5.6.1
  ipywidgets      : 7.5.1
  nbformat         : 5.0.4
  traitlets           : 4.3.3

conda --version: conda 4.8.2

After installing beakerx using pip and beakerx install:
beakerx --version: 1.4.1

Till this point everything is working, but when I tried to install lab extension
jupyter labextension install beakerx-jupyterlab@1.4.1
it fails to open lab UI with this error:

Uncaught TypeError: Cannot read property 'name' of undefined
    at JupyterLab.push.2dC9.Application.resolveRequiredService (index.js:191)
    at index.js:149
    at Array.map (<anonymous>)
    at JupyterLab.push.2dC9.Application.activatePlugin (index.js:149)

    at Array.map (<anonymous>)
    at JupyterLab.push.2dC9.Application.start (index.js:274)
    at main (index.out.js:1107)

If we don't install lab extension, lab UI will open but in the notebook we are seeing this error:
Error displaying widget: model not found

Is it broken? Or Am I missing something?
Does beakerx not support JupyterLab 2.x yet?

[ildipo]

Not yet supported. We are working on it

[haloforensics]

Hello,

Is there an ETA for JupyterLab 2.x support?

Thanks!

[karlduderstadt]

We also received the same error. We are very eager to start using the plots with Jupyterlab 2.x. Can we help by testing something?

[haloforensics]

Just checking back in to see if there is an ETA for JupyterLab 2.x support?

[feldoh]

Same issue here. @ildipo is there an ETA or beta version we could try or help with.

[iynehz]

Same here. Now beakerx is the only blocker for us to adopt Jupyterlab 2. I see there is a similar ticket #8246 but that's not moving..

[Ben-Epstein]

@ildipo are there plans to add support for Jupyterlab 2? Jupyterlab 3 is out now.

[dstieglitz]

We're happy to help as well if folks want to collaborate.

[dstieglitz]

Folks, we're coordinating a loose group to tackle this, please feel free to reach out to me for an invite to our Slack group.

Just ran into this and spent some time debugging before finding this issue.

Given that JupyterLab 3.x has been out for a couple of years, and that JupyterLab 4.x is in alpha, I would recommend prominently featuring on the BeakerX homepage the fact that only JupyterLab 1.x is supported. The "Installation for Jupyter Lab" section would be a good place for this.

I've opened up a PR here: twosigma/beakerx-www#58
