Set NODE_ENV before launching karma server

[plecos]

When karma server is being launched, I am seeing this error:

ERROR [karma-server]: UncaughtException:: error:0308010C:digital envelope routines::unsupported

Am running this on an Angular 7 project.

I know I can solve this by setting

NODE_OPTIONS=--openssl-legacy-provider

but how can I do this within the Karma Test Explorer extension?
