AkousaERR_OSSL_EVP_UNSUPPORTEDAn OpenSSL operation is unsupported, typically because Node.js 17+ uses OpenSSL 3.0 which disables legacy algorithms.
Node.js 17+ uses OpenSSL 3.0 which disables legacy cryptographic algorithms by default (MD4, some older hash functions). Older packages that depend on these algorithms will fail.
Start Node.js with --openssl-legacy-provider flag. Or set the environment variable: NODE_OPTIONS=--openssl-legacy-provider. The better long-term fix is to update the package that uses legacy algorithms to a version compatible with OpenSSL 3.0.
// Fix: node --openssl-legacy-provider app.jsSyntaxError: Applying delete to unqualified name in strict modeThe delete operator was used on a plain variable name in strict mode, which is not allowed.
ERR_HTTP2_STREAM_ERRORAn error occurred on an HTTP/2 stream.
EvalErrorAn error related to the global eval() function. This error is rarely encountered in modern JavaScript.
