• [nitpick] Consider using a separator like an underscore (e.g. f'retry_{request.unique_key}') to improve the readability of the unique_key.

new_request = Request.from_url(request.url, unique_key=f'retry{request.unique_key}')

• If response.read() returns bytes, consider decoding the response (e.g. using response.read().decode('utf-8')) before passing it to json.loads to avoid potential errors.

data = json.loads(response.read())

Lately, we've been getting a lot of questions about error handling or related issues.

Any ideas on how to improve the examples or additional examples are welcome.

Good idea, thanks!

We should add a similar guide to the JS version too I guess, would you be up for that too Max?

[Mantisus]

would you be up for that too Max?

I hardly ever write in JS.

I think that the code samples I can produce are hardly worth showing to anyone 😅

[B4nan]

All right, no worries, someone else can handle that.

It's great, thanks 🙂 .
