I have a log that contains the following output in the message field:

NULL

I need to parse only part of the fields from a given field:

• Host:
• x-user-id:
• each field in {“description”:{“rate-limit-by-x-user-id-coupon-create”:”pass”,”known-x-client-name-coupon-create”:”pass”},”score”:{“without_weight”:100.0,”weighted”:100.0,”weighted_softmax”:100.0}}

This is what i trying to do:

- type: log
  enabled: true
  paths:
    - /var/log/project_log/general_info.json
  processors:
    tokenizer: '%{Host} %{x-user-id}'
    field: "message"
    overwrite_keys: true
    target_prefix: ''

but the output remained the same and did not change
