Custom component fails to load

[q20]

Hi there

Since restarting my Home Assistant Core installtion this morning, I can no longer control my Nuki devices via HA as the integration fails to load:

Here's a snippet from the debug log:

Traceback (most recent call last):
  File "/usr/local/lib/python3.11/site-packages/requests/models.py", line 971, in json
    return complexjson.loads(self.text, **kwargs)

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

FYI, I was running Home Assistant 2023.6.1. I have just updated my container to 2023.6.2 and the component still fails to load.

Case closed: this turned out to be a problem with the Nuki Opener - after a factory reset, this Custom Component was once more able to connect to the Bridge successfully. 👍
