DeprecationWarning: Calling promisify on a function that returns a Promise is likely a mistake.

Genhan

Recently, our jsReport application has been generating a large number of the following DeprecationWarning messages. We are currently using jsReport version 4.3.1.

(node:3268) [DEP0174] DeprecationWarning: Calling promisify on a function that returns a Promise is likely a mistake.

I am wondering whether upgrading to the next minor version might resolve this issue. Although these are only warnings, the high volume is significantly cluttering our error logs.

This is likely because you have updated the nodejs.

You have several options.

downgrade back nodejs
suppress warnings node --no-deprecation server.js or env NODE_NO_WARNINGS=1
update jsreport, there seems to be no such warning in the latest jsreport, latest nodejs
