Yacron HTTP server failing with: KeyError: "Key not found: 'Accept'"

[vcajes]

• Yet Another Cron version: 0.11.2
• Python version: the one bundled on the tagged 0.11.2 on the release page
• Operating System: debian-stable

Description

The web listen config fails to parse requests coming from the kubernetes health checks.

What I Did

The yacron config

web:
  listen:
    - http://0.0.0.0:8072

The kubernetes healt check config:

        readinessProbe:
          httpGet:
            path: /status
            port: 8072
            scheme: HTTP

The output logs:

INFO:aiohttp.access:10.101.111.72 [22/Apr/2021:16:35:57 +0000] "GET /status HTTP/1.1" 500 244 "-" "kube-probe/1.19"
ERROR:aiohttp.server:Error handling request
Traceback (most recent call last):

  File "multidict/_multidict_py.py", line 69, in getone
KeyError: "Key not found: 'Accept'"

Apparently it doesn't know how to pare the Accept header or something.

Thanks team!

Ah, yes, looking at the line in question, it is obvious that it would crash if the Accept header is missing. Is a simple fix.

Awesome, thanks @gjcarneiro ! When are you planning to make a release binary with this fix included? This will allow use to with kubernetes :)
