This issue is in fact related to TS and independent of the JupyterLab version. I change the name of the issue accordingly.

Did you try to increase the timeout for your test ? You can do this in the `@testbook` decorator: `@testbook('/path/to/notebook.ipynb', execute=True, timeout=240)`

I don't know exactly what fixed it (perhaps #90) but serving bitshuffle compressed datasets now works :slightly_smiling_face:

In h5web, the aspect ratio setting is saved when the user changes it which seem to alleviate the issue at hand. Is it reset each time you load a dataset...

In fact, I get the same error (Jupyterlab 1.2.6, jupyterlab-hdf5 0.4.0) whatever the extension of the file... Maybe the issue is not solved yet ?

This is usually due to the server extension not enabled/installed. Could you see if `jupyterlab_hdf` is present and activated (`OK`) when running `jupyter serverextension list` ?

- Can you try `import jupyterlab_hdf` in a Python console to see if it works ? - How did you install the extension ? Can you try in a fresh...
