Vector: Tutorial on https://vector.dev/guides/integrate/sources/syslog/loki/#start-vector failed

The tutorial on:

https://vector.dev/guides/integrate/sources/syslog/loki/#start-vector

Here's what went wrong:
Jun 10 14:45:32.435 ERROR vector: Configuration error: "vector.toml": missing field encoding for key sinks.out

[binarylogic]

Thanks for reporting!

[nadgobpx01]

adding this line fixed it:

#Encoding
encoding.codec = "json" # optional, default

[binarylogic]

Thanks, going to reopen this so we can fix the docs.

@nadgobpx01 have you tried this with their cloud offering?

This:

[sinks.loki]
  # General
  type = "loki"
  inputs = ["docker", "syslog"]
  endpoint = "https://logs-prod-us-central1.grafana.net"

  # Auth
  auth.user = "4902"
  auth.password = "<api token here>"
  auth.strategy = "basic"

  # Encoding
  encoding.codec = "json" # optional, default

  # Labels
  labels.job = "varlogs"

gives 400 bad request error in vector sink log :(

which is very strange since

~ ❯ curl https://4902:therewasmytoken\=\[email protected]                                                                                                                                                    8s 16:22:45
OK

Tutorials were correct, encoding should be optional.

Fixed with #2796.
