Python client subscript error

Here is what I see from a fresh install of the python client from https://gitlab.com/cipres/misfin:

$ misfin listen-as k0stk.pem

Traceback (most recent call last):

File "/usr/local/bin/misfin", line 5, in <module>

(Bubble tip: there's a Search feature at the bottom of the page. I just put your error message in the search: "TypeError: 'type' object is not subscriptable".)

@BBSman There is no "listen-as" command, it's either "receive-as" or "serve" (to run a full server).

I haven't tried this with python 3.7, it's recommended to use at least python 3.9. Try it with python 3.9 with "misfin receive-as mycert.pem"

Thanks for the hint. Unfortunately I don't see this search link anywhere.

Installing python 3.9 is not an option for me at this time. And that's a lousy strategy for fixing a coding issue.

The problem with the python client appears to be the list[Identity] construct in the Letter init

It turns out the issue was that string.removeprefix (which is only used on line 46 in misfin.py) was introduced in v3.9

I replaced: raw = raw.removeprefix("misfin://") with raw = raw[9:] and got things working.

Edit: I also had to replace list[Identity] with Identity on letter.py line 25
