docker container json log showing INFO and WARNING statements with stderr as stream

问题

On <Container Id>-json.log finding some entries with INFO and WARNING with stream as stderr. Actually, these have to be with stream as stdout. Can anybody give a clue to where exactly I need to look into this? Is this docker related configuration or my application related configuration? Example,

{"log":"[2020/02/20-08:50:26,557]-[**INFO**   ]-[362]-[testlogger]--4: 202a68dfd8621ee9de1a7ff4\n","stream":"stderr","time":"2020-02-20T08:50:26.55867314Z"}
