The first problem is that this Python version seems not to
like assignments embedded in if statements:

File "t/oauth_server.py", line 319
if err := self._get_param("error_code", None):
^
SyntaxError: invalid syntax

I was able to work around that with the attached quick hack.
But then I get

Traceback (most recent call last):
File "t/oauth_server.py", line 19, in <module>
class OAuthHandler(http.server.BaseHTTPRequestHandler):
File "t/oauth_server.py", line 26, in OAuthHandler
JsonObject = dict[str, object] # TypeAlias is not available until 3.10
TypeError: 'type' object is not subscriptable

which I have no idea how to work around.
