Loki Grafana - promtail pipeline breaks after recreating the secret

[tejas115]

After watching the Grafana Loki training, I tried to follow the instructions in the promtail pipeline training but my log differs from the one shown in the video. No “log:” property to search as shown in the video, my starts with “level”. secondly after I recreated the secret my logs stopped flowing, so maybe the promtail config or secret messed it up. Trying to figure out what broke. Has anyone else had similar experience? should I be using “level” instead of “log” property. What should my promtail.yaml look like if I should make a change. Thanks in advance.
promtail.yaml - below

  - match:
      selector: '{app="api"}'
      stages:
        - json:
            expressions:
              log:
        - json:
            source: log
            expressions:
              code: code
              method: method
        - labels:
            code:
            method:

I was able to resolve it by flattening the expression from log in the video to just directly code and method and make it work.
