I am using DymoJS (https://www.npmjs.com/package/dymojs) to print labels on my local machine and I get this error:

(node:26972) Warning: Setting the NODE_TLS_REJECT_UNAUTHORIZED environment variable to '0' makes TLS connections and HTTPS requests insecure by disabling certificate verification.

I tried installing ssl-root-cas (https://www.npmjs.com/package/ssl-root-cas) but that does not help. I also tried changing NODE_TLS_REJECT_UNAUTHORIZED to '1' in the dymojs library but it does not work either.

This warning appears once for each of the five JavaScript files that get run, and can be safely ignored (in a development environment) and does not affect the running of the tutorial.

modify the lines to set the “NODE_TLS_REJECT_UNAUTHORIZED” environment variable to one.

process.env["NODE_TLS_REJECT_UNAUTHORIZED"] = 1;
