Description
Using Python 3.9.1, 32-bit, and the current download of Sphinx. Documentation HTML output works pretty much normally, but the search feature crashes as indicated. Caused by any reference to functions in searchindex.js or searchtools.js failing. BUT... note that I had built documentation for these same modules a couple of years ago and everything worked just fine, so I copied the contents of that old _static directory with an old copy of your searchtools.js into the new _static directory and search now works. I don't have time to compare the old and new version of searchtools.js, but something clearly has changed and now triggers this error. BTW, the CORS error appears with EDGE, FireFox and Chrome.
