Misleading - $batch->getLastError() is false even on failure.

[chaslain]

Hello, I have an issue where, while using batch to add multiple journal entries, no error is indicated from $batch->getLastError() function.

Code:

$batch->Execute();
if ($batch->getLastError())
{
 // my code is not failing on errors!
 throw new Exception("problem!!!");
}

However, After calling execute and enumerating the results (in this case IPPJournalEntry) the Resulting ID Is null, and the accompanying $exception inside the batch is IntuitBatchResponse is populated.

Are batches then not transactional? Can some batch entries succeed while others fail within the same batch?

Proposal
$batch->ExecuteTransactional() which is all or nothing, and populating getLastError() in either case.

You can retrieve the error by enabling exceptions with throwExceptionOnError(true) like this:

try {
    $resultObj = $batch->throwExceptionOnError(true)
        ->Add(TypeAs::class(IPPIntuitEntity::class, $invoiceToCreate));
} catch (Exception $e) {
    dd($e->getMessage());
}

When an error occurs (e.g., a duplicate invoice number), the exception message will include details like:
