This is the warning
Per Releases | Node.js nodejs 12 will EOL on 2022-04-30. Please change the warning message’s display condition to be ahead of when you plan to drop support for nodejs 12, not three months before nodejs 12’s EOL date will come to pass.
I agree we could have done better here. What we mean to say is that executing analysis with NodeJS 12 is deprecated and will eventually be removed (unfortunately we don’t state when, or what version(s) are supported).
The answer to “which versions are supported” is NodeJS 14 and 16.
I’ve reached out internally to see if we can improve the messaging.
