Error message

account.manage.unsupported

What it means

BusinessException code account.manage.unsupported thrown by DbAccountAdminServiceImpl.requireAccountManager when Chat2DBContext.getAccountManager() returns null. Account management (create/drop/alter DB users, grants) is an SPI capability; if no IAccountManager plugin is registered for the current connection's DB type, the feature is unsupported.

Solutions

1. Confirm the target DB type has a registered IAccountManager plugin for your edition.
2. Use a supported DB type, or manage accounts through the DB's native tooling instead.
3. If developing a plugin, implement and register an IAccountManager for the dialect and ensure it is on the classpath.

Example fix

// before
account_execute({ dataSourceId, operation: 'CREATE_USER', ... })  // on unsupported DB type

// after: use a supported engine or manage users natively
// (e.g. via psql/mysql CLI on the target DB)

IAccountManager mgr = Chat2DBContext.getAccountManager();
if (mgr == null) {
    // skip account-management UI / return unsupported for this DB type
    return unsupported("account.manage.unsupported for this DB type");
}

public boolean accountManagementSupported() {
    return Chat2DBContext.getAccountManager() != null;
}

try {
    dbAccountAdminService.execute(command);
} catch (BusinessException e) {
    if ("account.manage.unsupported".equals(e.getCode())) {
        return unsupported("Account management is not available for this datasource type");
    }
    throw e;
}

When it happens

Trigger: Calling account preview/execute against a datasource whose DB type has no registered IAccountManager implementation in the SPI/plugin layer.

Common situations: DB type that does not support user management through this SPI (e.g. some file/embedded DBs, or engines without a plugin account manager); plugin module not loaded; community edition missing the account-management plugin for that dialect.
