Iteration through search results is broken

[ArtPoon]

To reproduce:

• search for "Canada" and limit collection dates to last three weeks (2022-11-16 as of today)
• when search results are rendered, use "Next" button to click through highlighted beads
• iteration breaks after attempting to step from 3rd to 4th result

Snippet from console:

Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'scrollIntoView')

Hm I'm having trouble reproducing this error.

Was not able to reproduce this error either. Do you know when this error occurred?

New data files were uploaded to the web server at ~9 am today. The node server would have been down for about 1-2 minutes so that could explain this error if a search was done at around that time.

I wrote the issue shortly after encountering the error, so that timestamp should be pretty close.

New data files were uploaded to the web server at ~9 am today.

I was looking at the wrong time before. New files were uploaded at 13:31 today, which was around the time the issue was opened

[ArtPoon]

Ok then that's a likely explanation. Would it be possible to have a 503 response trigger a pop-up for the user to know that the server is being updated and is temporarily unavailable?

[ArtPoon]

I'll close this and make a new issue about 503 response
