Libcoap depends on Aiocoap

[MathiasMeuleman]

Where are you using pytradfri (eg stand-alone, Home Assistant etc)

Stand-alone python script

Version of pytradfri

v10.0.0

Backend used (aiocoap, libcoap)

libcoap

What type of environment are you in, eg Dockerized, Raspberry PI, VirtualBox, WiFi network (give as much details as possible)

Running python 3.10 on Linux machine

Expected behaviour

Imports are resolved properly, script runs as normal

Actual behaviour

ModuleNotFoundError: No module named 'aiocoap' when importing pytradfri.api.libcoap_api.APIFactory.

In this PR a dependency on aiocoap was added to libcoap, which breaks the import. Downgrading to v9 resolves the issue.

@MathiasMeuleman in what file is this error raised? Can you please provide the full stacktrace?

[MartinHjelmare]

This is incorrectly typed:

pytradfri/pytradfri/api/libcoap_api.py

Line 216 in 1d716f3

output: Message, parse_json: bool = True

The libcoap api doesn't use aiocoap Message instances.

Here is the full stacktrace

Traceback (most recent call last):
  File "[...]/script.py", line 4, in <module>
    from pytradfri.api.libcoap_api import APIFactory
  File "[~]/local/lib/python3.10/site-packages/pytradfri/api/libcoap_api.py", line 10, in <module>
    from aiocoap import Message
ModuleNotFoundError: No module named 'aiocoap'

As @MartinHjelmare said, the dependency on aiocoap which imports Message is the culprit.

Thanks, I’ll try to have a look at this over the weekend.

[ggravlingen]

@MathiasMeuleman 10.0.1, including the fix, is on pypi now.

[MathiasMeuleman]

Sorry for the late followup, but thank you for the quick responses and fix!
