I have tried Filebeat 7.7.0 and 7.7.1, setup with the following filebeat.yml  
filebeat.inputs:

- type: container  
paths:
  - '/var/lib/docker/containers/_/_.log'  
json.keys\_under\_root: true  
json.add\_error\_key: true  
json.message\_key: log  
json.overwrite\_keys: true

processors:

- add\_docker\_metadata: ~

- decode\_json\_fields:  
fields: {"log"}  
target: "json"

output.elasticsearch:  
hosts: ["elasticsearch:9200"]  
indices:  
- index: "filebeat-%{[agent.version]}-%{+yyyy.MM.dd}"

logging.json: true  
logging.metrics.enabled: false

getting this error  
Error decoding JSON: invalid character

Any help on the same
