Error in PublisherQueryLanguageContextError.UNEXECUTABLE

Hello everyone i am getting this error how to solve this?
[PublisherQueryLanguageContextError.UNEXECUTABLE @ Only constant values and bound values are allowed in the haystack of IN.].

i am using this code :

$statementBuilder = (new StatementBuilder())
->where('AD_UNIT_ID IN ('.$excluded.')');

$reportQuery->setStatement($statementBuilder->toStatement());
$reportQuery->setAdUnitView(ReportQueryAdUnitView::HIERARCHICAL);

$reportQuery->setDateRangeType(DateRangeType::TODAY);

$reportJob = new ReportJob();
$reportJob->setReportQuery($reportQuery);

        $reportJob = $reportService->runReportJob($reportJob);
        $exportFormat = 'CSV_DUMP';
        $reportJobId = $reportJob->getId();
        $reportDownloader = new ReportDownloader($reportService, $reportJobId);

if ($reportDownloader->waitForReportToFinish()) {
// set download option
$options = new ReportDownloadOptions();
$options->setExportFormat($exportFormat);
$options->setUseGzipCompression(FALSE);

        $downloadUrl = $reportService->getReportDownloadUrlWithOptions($reportJobId, $options);

The issue provides only an inline PHP example using StatementBuilder and ReportQuery, with no repository file or test named. Start by reproducing the report query around the AD_UNIT_ID IN clause and determine the expected input and successful report-job behavior; done means the query runs without the UNEXECUTABLE error.
