"Download Auspice JSON" does not work

[ivan-aksamentov]

Current Behavior

When loading a nwk file:

((A:0.1,(B:0.2,C:0.3,D:0.4)BCD:0.5)ABCD:0.6,(E:0.7,F:0.8)EF:0.9,(G:1.0,H:1.1,I:1.2,J:1.3)GHIJ:1.4)ABCDEFGHIJ:1.5;

The tree is displayed fine.

But when clicking on "Download Auspice JSON" in the "Download data" dialog, the download does not happen.

A notification toast is displayed with "Preparing Auspice JSON(s) for download: " (without filename)

I also tried with some random Auspice JSON tree I had laying around, and download did not work either.

My goal was to obtain a canonical nwk-to-auspice conversion in order to reproduce and test the same conversion in another project. But I left empty handed :(

I checked on nextstrain.org and for SARS-CoV-2 the JSON download works. It also displays a filename in the toast.

Expected behavior

Download starts when "Download Auspice JSON" is clicked

How to reproduce

Steps to reproduce the current behavior:

1. Open auspice.us
2. Drop a nwk file posted above
3. Click "Download data"
4. Click "Download Auspice JSON"
5. Observe that doesnload does not start

Possible solution

(optional)

Your environment: if browsing Nextstrain online

Chromium 126

Your environment: if running Nextstrain locally

Ah, thanks for flagging this feature doesn't work in auspice.us!

Auspice is not generating the JSON but tries to fetch the original dataset based on the URL. Auspice should do a better job here of notifying that no datasets were available for download. Maybe we should even hide the download option here.

auspice.us does convert the newick tree to an Auspice JSON so we might be able to surface that just within auspice.us? Not entirely sure what the UI/UX would be like here.
