issue [null] null: null maybe caused by structlog or colorama

[fraser-langton]

When the plugin is disabled the [null] null: null text does not show, thought maybe it was from colorama using the ansi chars. I did a few things to try and fix like ensuring a reset ansi character was before the json but that didn't help. I tried adding a new line, but that stopped the json folding working at all.

here is some raw ansi that caused the issue

\x1b[2m2025-01-24 02:46:20\x1b[0m [\x1b[33m\x1b[1mwarning  \x1b[0m] \x1b[1mNot Found: /au/api/v1/customers/club/\x1b[0m [\x1b[0m\x1b[1m\x1b[34mdjango.request\x1b[0m]\x1b[0m\x1b[0m {"filepath": "/opt/venv/lib/python3.12/site-packages/django/utils/log.py:241"}

I checked and the ansi looks valid and should have this effect (I used xml like tags to illustrate)

<dim>2025-01-24 02:46:20</dim> 
[<yellow><bold>warning</bold></yellow>] 
<bold>Not Found: /au/api/v1/customers/club/</bold> 
[<bold><blue>django.request</blue></bold>] 
{"filepath": "/opt/venv/lib/python3.12/site-packages/django/utils/log.py:241"}

Ok I think I see why, it wasn't quite clear form the docs that there were reserved keywords in the log event (level, timestamp, message) and so that's why they are all null for me

Perhaps allow a option to disable formatting in the plugin? ie then I can leave the formatting up to myself?

Also perhaps make timestamp and level optional

@fraser-langton Thank you for reporting the issue! As you say, the display of [null] null: null is due to this plugin.

Normally, this plugin only tries to format and display when the entire line is JSON. However, perhaps due to the ANSI color code, it may not be able to correctly recognize the line break.

It is difficult to fundamentally fix this behavior, but it is possible to temporarily disable the formatting from the console context menu. Is this a solution for you?

I found even turning off colours didn't fix it, it then just displayed the json raw

app-1  |  {"correlation_id": "49192939521365a20be056a9d71fbaf4", ...}

however adding a ansi reset all char before each log fixed it, i made a structlog processor

def pretty_json_log(logger: WrappedLogger, name: str, event: str) -> str:
    return f"{_ColorfulStyles.reset}{event}"
