To fix the Node.js 17.0.1 Gatsby error – "digital envelope routines::unsupported … ERR_OSSL_EVP_UNSUPPORTED" error, we use a legacy SSL provider to let us use the SSL algorithm or key size used by Gatsby.
For instance, we write
{
"scripts": {
"build": "export NODE_OPTIONS=--openssl-legacy-provider; gatsby build"
}
}
in package.json rto modify the build script to set the NODE_OPTIONS environment variable to --openssl-legacy-provider to use an old version of OpenSSL to let Gatsby use an old algorithm or key size.
