Binderhub: Binder not opening a specific file when directed to (Jupyter Lab)

Created on 5 Oct 2020 · 4Comments · Source: jupyterhub/binderhub

Bug description

Binder is not opening a specific file (with Jupyter Lab) when directed to it

Example: https://mybinder.org/v2/gh/melaniewalsh/Intro-Cultural-Analytics/master?urlpath=lab/tree/book/Data-Analysis/Pandas-Basics-Part1.ipynb

Expected behaviour

Binder opens a specific file when it is directed to

Actual behaviour

Instead Binder opens in the root directory. It looks like at the last second ?clone is added to the end of the url, which might be the problem?

How to reproduce

Go to this Binder link https://mybinder.org/v2/gh/melaniewalsh/Intro-Cultural-Analytics/master?urlpath=lab/tree/book/Data-Analysis/Pandas-Basics-Part1.ipynb
See that it's opening in the root directory (but weirdly if you refresh the page, then the Pandas-Basics-Part1.ipynb file opens)

Hi there 👋 !

When I click your link I end up at the following:

Which looks like it worked. The URL I end up at is https://hub.gke2.mybinder.org/user/melaniewalsh-in-tural-analytics-btp7mufo/lab. Could you post the one you end up? Maybe one of the clusters behind mybinder.org behaves differently, which we could spot from the different hostnames in the URL. I am using Firefox 82.0b3 (64-bit) on OSX and you?

Thanks for trying it out, @betatim! And, yes, it looks like it worked for you. Good to know that it's working correctly sometimes.

I just tried the same link a handful more times, and Binder opened the filepath correctly a couple of times, but it still opened in the root directory at other times.

These are two of the URLS from when Binder opened in the root directory:

I'm using Chrome Version 85.0.4183.121 (64-bit) on OSX.

We have seen this on our instance and noticed that the expected behavior works in Chrome Incognito mode. I have not figured out how the workspaces/auto-[x]/ gets inserted into the URL.
