• I have tried restarting my IDE and the issue persists.
• I have updated to the latest version of the packages.
• I have read the FAQ and my problem is not listed.

Expected Result

No no-undef error should be thrown.

Actual Result

functions/test.js
   6:31  error  'now' is not defined               no-undef

Additional Info

The check no-undef only triggers the error in class methods with default arguments. If I move the test function out of the class, then no exception is reported.
