When running locally, or in other situations that may involve self-signed certificates, you may run into the error: The request failed with error code "DEPTH_ZERO_SELF_SIGNED_CERT".
To solve this, you can disable Node.js' rejection of unauthorized certificates by adding the following to .env.development:
NODE_TLS_REJECT_UNAUTHORIZED=0Please note that you need to add dotenv, as mentioned in this guide, to expose environment variables in your gatsby-config.js or gatsby-node.js files.
CAUTION: This should never be set in production. Always ensure that you only enable NODE_TLS_REJECT_UNAUTHORIZED in development with gatsby develop.
