Sphinx extension error (sphinxprettysearchresults): for event 'build-finished', error "exception: name 'unicode' is not defined"

In my Sphinx project (Python 3.12.1, Sphinx 7.2.6 under Windows 10), when trying to generate the output HTML code using the "sphinx-build -E" command, I get the following persistent error:

"Extension error (sphinxprettysearchresults):Handler <function build_search_snippets at 0x0000022451ACBF60> for event 'build-finished' threw an exception (exception: name 'unicode' is not defined)".

Earlier in 2023-2024, I resolved a bunch of similar errors.One of them:

"Extension error (sphinxprettysearchresults):Handler <function add_custom_source_link at 0x000001B2A7D96CA0> for event 'builder-inited' threw an exception (exception: name 'os' is not defined)"

I resolved the issue by adding the following three lines of code at the beginning of the file Python\Lib\site-packages\sphinxprettysearchresults_init_.py:

import osimport syssys.path.insert(0, os.path.abspath('.'))

I ENTERED THE FOLLOWING:

...\root\myrepo>sphinx-build -E d:\Luxoft\root\myrepo\en ...\root\myrepo-build\output\en

I GOT THE FOLLLOWING:
