after updating kolo to 2.33.8

it used to be working fine before that version

something to note

the first request goes well and kolo vs extension does capture it

the server is still up but the following requests fail

what I do now after each requests I comment and uncomment the middleware line everytime I want to use kolo

👋 Thanks for the report – are you sure this issue stems from Kolo? Asking because I've not seen this error before and it doesn't immediately seem like kolo is the culprit.

is it possible another package was upgraded alongside kolo that could be causing this?

What was the last kolo version that worked for you?

[wilhelmklopp]

Had a quick chat with Claude about your stacktrace and it seems to suggest that from Python 3.9 onwards types.SimpleNamespace becomes hashable. So if upgrading python versions is an option for you, i'd recommend checking if this error still happens on on 3.9 or newer

[EssaAlshammri]

yeah sorry

I've just tried it with another project and it works like a charm

but the thing is it was working with this one before and I thought it was because of the update. the project hasn't changed at all and I've already tried down to 2.33.4 and still not working.

I'm pretty sure now it's my setup not kolo
