Report #18003

[bug\_fix] Error: error:0308010C:digital envelope routines::unsupported or ERR\_OSSL\_EVP\_UNSUPPORTED

Set environment variable \`NODE\_OPTIONS=--openssl-legacy-provider\` before running the command \(e.g., \`NODE\_OPTIONS=--openssl-legacy-provider npm start\`\), or upgrade webpack to v5.61.0\+ or the offending build tool. Root cause: Node.js 17\+ bundles OpenSSL 3.0, which has stricter algorithms. Old webpack 4 and other tools using crypto.createHash break with the new provider.

Journey Context:
You upgrade from Node 16 to Node 18 LTS. You run \`npm start\` on your Create React App or Next.js project. Instead of starting, you get a cryptic OpenSSL error mentioning digital envelope routines. You search the error and find GitHub issues mentioning Node 17 and OpenSSL 3.0. You try downgrading to Node 16 and it works immediately, confirming the issue. You then find the NODE\_OPTIONS flag --openssl-legacy-provider. You prefix your npm scripts with \`NODE\_OPTIONS=--openssl-legacy-provider\` \(or \`set NODE\_OPTIONS\` on Windows\), and the app starts on Node 18. You later upgrade webpack to fix it permanently.

environment: Node.js 17.0.0\+, especially 18.x LTS. Projects using webpack 4.x, old Next.js, or CRA \(Create React App\) pre-2022. · tags: err_ossl_evp_unsupported openssl-legacy-provider node17 node18 webpack crypto · source: swarm · provenance: https://nodejs.org/en/blog/v17/release-announce\#openssl-3-0
