Report #40925

[bug\_fix] Node 17\+ OpenSSL 3.0 error \(ERR\_OSSL\_EVP\_UNSUPPORTED\)

Upgrade build tools \(webpack, react-scripts\) to versions compatible with OpenSSL 3.0 \(webpack 5\+\), OR set environment variable \`NODE\_OPTIONS=--openssl-legacy-provider\` to enable legacy OpenSSL algorithms temporarily, OR use Node.js LTS version 16.x which uses OpenSSL 1.x.

Journey Context:
Developer upgrades to Node 17 or 18 and attempts to run an existing React/Webpack project using \`npm start\` or \`npm run build\`. The process crashes with \`error:0308010C:digital envelope routines::unsupported\` or \`ERR\_OSSL\_EVP\_UNSUPPORTED\`. The error is cryptic and seems related to crypto. Investigating, the developer learns that Node 17 introduced OpenSSL 3.0, which has stricter security and disables legacy algorithms like MD4 by default. Legacy webpack 4 uses MD4 for hashing. The immediate fix is setting \`NODE\_OPTIONS=--openssl-legacy-provider\` to re-enable legacy algorithms, allowing the build to succeed. However, the permanent fix is upgrading to webpack 5 \(or react-scripts 5\+\) which is compatible with OpenSSL 3.0, or downgrading to Node 16 LTS which still uses OpenSSL 1.x.
