Yeah, that error with ERR_OSSL_EVP_UNSUPPORTED has tripped up loads of people — it’s due to changes in Node.js 17+ where OpenSSL 3.0 is more strict. Quick fix: try setting the environment variable before running your project with:
export NODE_OPTIONS=–openssl-legacy-provider
Or if you’re on Windows (CMD), run:
set NODE_OPTIONS=–openssl-legacy-provider
Then try npm start again.
