Error message

--data-source-id cannot be combined with temporary connection parameters

What it means

CliDomainException code invalid_connection_test_args from validateConnectionTestRequest: when request.dataSourceId is present AND any temporary connection field (dbType, url, host, port, database, user, password, serviceName, serviceType) is also non-blank. The connection test is intentionally one-mode-only.

Solutions

1. To test a saved datasource: pass ONLY dataSourceId.
2. To test a temporary connection: omit dataSourceId and provide dbType plus connection fields.
3. Audit the CLI/script invocation for accidentally-set default values on temporary fields.

Example fix

# before
test --data-source-id 5 --host db.prod --port 3306

# after (test saved datasource only)
test --data-source-id 5

boolean hasId = request.getDataSourceId() != null;
boolean hasTemp = Stream.of(request.getDbType(), request.getUrl(), request.getHost(),
        request.getPort(), request.getDatabase(), request.getUser(), request.getServiceName(), request.getServiceType())
        .anyMatch(StringUtils::isNotBlank) || request.getPassword() != null;
if (hasId && hasTemp) {
    throw new IllegalArgumentException("Choose either dataSourceId or temporary fields, not both");
}

public boolean isTemporaryMode(CliConnectionTestRequest r) {
    return r != null && r.getDataSourceId() == null;
}

try {
    cliDataSourceService.testConnection(request);
} catch (CliDomainException e) {
    if ("invalid_connection_test_args".equals(e.getCode())) {
        return badRequest(e.getMessage());
    }
    throw e;
}

When it happens

Trigger: Calling connection-test with both a dataSourceId and host/url/user/etc., expecting the temp fields to override the stored datasource.

Common situations: CLI flag mix-up: passing --data-source-id together with --host/--url; an automation script defaulting fields while also referencing a saved datasource.
