"Length problem" error in

[bsnuggs76]

I'm opening a 1441 page PDF and using PdfTextExtractor_getTextFromPage to search for certain keywords in each page. The call to PdfTextExtractor_getTextFromPage is failing showing only the message "Length problem" on the QShell screen on exactly 107 of those pages. I'm using monitor/on-error to stop it from abnormally ending, but I can't figure out what problem it has with these 107 pages. I thought it was a random memory allocation error, but it's always the same pages.

Any thoughts?

dow airPage <= airPages;
  #lcerr = *off;
  monitor;
    airString = PdfTextExtractor_getTextFromPage(airExtractor:airPage);
  on-error;
    srltext80 = 'Error occurred during Text Extraction on '
     + 'Page ' + %trim(%editc(airPage:'Z'));
    exsr add_log;
    #lcerr = *on;
  endmon;
  if not #lcerr;
    airBytes32k = String_getBytes(airString);
    #lcpage = airPage;
    #lcpagetxt32k = airBytes32k;
    exsr search_page;
  endif;
  airPage = airPage + 1;
enddo;
