I have the following PHP script that I have inherited, I am getting the following error but I cannot find the issue.

 $headerLineCount && strlen(trim($referenceNo)) > 0){
            $isFirstRow = false;
            $recordNo += 1;
            
            $sqlInsertBody .= "

            ";

              $resultInsert = oci_execute($stmtInsert);

                echo var_dump($errorInsert).PHP_EOL;

The job is failing see below, 1 thing that I have noticed is that the next sequence number is blank.
