Use different env then NODE_ENV for disabling error masking

Is your feature request related to a problem? Please describe.

Setting NODE_ENV to a different value then production is regarded an anti pattern (see https://nodejs.org/en/learn/getting-started/nodejs-the-difference-between-development-and-production).

Describe the solution you'd like

Please use a different variable to not mask errors in dev. Like APP_ENV or something similar.
