[SOLVED] Bunyan logger not printing "ERROR" log level in aws cloudwatch log

Bunyan logger not printing "ERROR" log level in aws cloudwatch log

We are using Bunyan lib for aws lambda function for cloud watch. I am observing , when I print Bunyan logger with status error , it is printing error format as follows

{
    "name": "test-abc",
    "serviceID": ".......................",
    "requestID": "........................",
    "hostname": "................",
    "pid": 8,
    "function": "_testStore",
    "level": 50,
    "msg": "store_id is missing",
    "time": "2020-11-16T19:17:41.109Z",
    "v": 0
}

while, when I log the error using console.error function , I am getting error log in the below format

2020-11-16 13:41:27.357 (-06:00) a..... ERROR store_id is missing

As ERROR logLevel tag in cloud watch help , to generate cloud error matrix, how could I use Bunyan for the same to print ERROR tag before the JSON object.

Solution

Buyan format uses level as a decimal number where level error means 50.
