Proposed fix: [Node 'mysql' (mysqljs) with MySQL 8+] 'ER_NOT_SUPPORTED_AUTH_MODE: Client does not support authentication protocol requested by server' / 'MySQL is requesting the caching_sha2_password
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Switch to the maintained 'mysql2' package (API-compatible for most uses) which supports caching_sha2_password. Downgrading the account to mysql_native_password is a dead end on MySQL 8.4+/9.x.
Option: Use mysql2 [evidence: documented_workaround]
Applies when: See record scope.
Steps:
1. npm install mysql2
2. Replace require('mysql') with require('mysql2') (or mysql2/promise)
Expected: Command proceeds without the error.
Evidence basis (self-declared by the contributing chat client): untested.
