node 16 is current active lts. Attempting to upgrade to 16.13.1 yields following error at steal transpilation step

could be an issue with StealJS - I think it might required an upgrade to 2.x for Steal to work with Node14/16 @tobiasnteireho

[tobiasnteireho]

This error still occurs with steal 2 and steal 2 yields a bad engine error in node 16 stealjs/steal-tools#1161

[tobiasnteireho]

looks like setting sourcemaps:false in Gruntfile resolves this. Steal upgrade works.
