Not a bug in library itself but on docs webpage. The issue is that the search bar on documentation page (fastapi.tiangolo.com) does not work on safari browser on mac. Clicking on search bar shows Initializing search and then nothing else happens.
It works on chrome though on the same system.
Here's the screenshot:

Works on Safari 13.1. Could you try again in a Private Window.
Worked in the new private window. However opened a new tab on the same window and again the same problem. I also have Safari 13.1.
Tried the same on Chrome Incognito. Surprisingly the search didn't work. Opened a new tab on the same window. Didn't work there as well.
Tested on Chrome, Safari, Firefox. Working only for Mozilla. Potential bug
If an incognito window works it might be that you have stale cached assets in your browser.
Please remove the cache for the docs site and try again: https://developers.google.com/web/tools/chrome-devtools/storage/cache
Assuming the original issue was solved, it will be automatically closed now. But feel free to add more comments or create new issues.
Hi, this issue has yet not been solved and it does not work on safari, chrome, firefox icognito or not. Please take necessary action.
@mundranaitik What word did you try? Have you tried in another network? It's working fine for me in Chrome.
Now its working for me thnx. @phy25
The search hangs in 'Initializing search' state, while debugger shows the following error.
Source map error: Error: request failed with status 403
Resource URL: https://sidecar.gitter.im/dist/sidecar.v1.js
Source Map URL: sidecar.js.map
This happens like 9/10 times I try to load the site. Even in incognito mode, all browser extensions disabled.
UPD: I tried to turn off built-in Firefox tracking blocks. The search is sporadically available, but the error is always present. It seems that the search is available only on the first page reload after changing element blocking policies (either to stricter or more tolerant).
This was probably related to an older version of the theme Material for MkDocs. But I think the newer versions should work fine.
