Use --openssl-legacy-provider

or npm audit fix --force

Reason For The Error

In Node.js v17, the Node.js developers closed a security hole in the SSL provider. This fix was a breaking change that corresponded with similar breaking changes in the SSL packages in NPM. When you attempt to use SSL in Node.js v17 or later without also upgrading those SSL packages in your package.json, then you will see this error.

node --openssl-legacy-provider node_modules/.bin/gatsby build
node --openssl-legacy-provider node_modules/.bin/gatsby develop

Alternatively, set the engine field in your package.json and set requirement for node to v16:

"engines" : { 
    "node" : ">=16.0.0 <17.0.0"
}

To enforce this via npm you need to create an .npmrc file with the value:

engine-strict=true

This raises an error for not having the right version of node when users run npm install
