Cause

This is a known issue in Winston 3.14.

It is resolved in 3.14.2. The issue will no more persist with our NodeJS Agent as it will always pick latest Winston version which is 3.15.0.

Resolution

If you are running the pre-release of NodeJs Agent, please contact Broadcom Support to get a compatible Agent that works in 3.14.2 Winston.
