Ignore SSL certificates when fetching GraphQL data

[maxyudin]

I am on the localhost with *.test domains for each project. Following the guide by Cecile Muller I've created self-issued certificates for testing purposes. Now I'm experimenting with Next.js and facing the problem when I can't fetch the GraphQL output from my localhost-based WordPress because of "FetchError: request to XXXXX failed, reason: unable to verify the first certificate". Errno and error code are "UNABLE_TO_VERIFY_LEAF_SIGNATURE". All my browsers eats this certificate like their own food, but not node-fetch and others from NodeJS.

How can I ignore certificate verification when fetching the data? I can't see any CLI option or config string to do this like, e. g., curl can do. Should I write (copy/paste) a script to include it somewhere?

ssl-root-cas looks like a solution, but I can't figure out how to nail it to the brand-new starter project.
