I keep getting an 'UnhandledPromiseRejectionWarning' when trying to run pagecrypt using npm..

This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag `--unhandled-rejections=strict` (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode).

(node:1608) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

Am I missing something?

Hi! Are you using Node.js v15 or newer?

I recommend using Node.js v16, which will be the next LTS release in October 2021.

node -v

Let me know if this helps! 🙂

I added the recommended Node.js versions to package.json a while back, but that's not clear enough.

I'm adding a note to the README file to make sure more people see it :)

@pm-Architect I'll assume upgrading Node.js solved your issue - let me know if you find anything else.

Have a nice day! :)

Yes it did. Thanks! 😄
