Report #7302

[bug\_fix] error:0308010C:digital envelope routines::unsupported

Set environment variable NODE\_OPTIONS=--openssl-legacy-provider before running the build command \(e.g., NODE\_OPTIONS=--openssl-legacy-provider npm run build\). Root cause: Node.js 17\+ ships OpenSSL 3.0 which disables legacy algorithms \(MD4\) used by webpack 4's crypto.createHash; the flag re-enables the legacy provider.

Journey Context:
You upgrade to Node 18 for security patches. You run npm run build on a legacy React project using webpack 4 \(react-scripts 4\). It crashes with 'error:0308010C:digital envelope routines::unsupported' and a long OpenSSL stack trace. You search and find it's related to OpenSSL 3.0 in Node 17\+. You consider downgrading Node, but instead you try setting NODE\_OPTIONS=--openssl-legacy-provider. You export it in your shell, run the build again, and webpack 4's hashing now works. You add it to your package.json scripts permanently for the legacy project.

environment: Node.js 17, 18, 19\+ \(OpenSSL 3.0\), projects with webpack 4, vue-cli 4, or old react-scripts. · tags: openssl err_ossl_evp_unsupported webpack node18 legacy-provider · source: swarm · provenance: https://nodejs.org/api/cli.html\#--openssl-legacy-provider
