Laserfiche Forms Error: LFF5437-STRErrorGeneratePage

Forms

Updated July 11

asked on August 31, 2023

We have a form that users use to upload documents to our Laserfiche repository. The form is working and users are uploading many documents per day.

We noticed that there are about 18 form upload tasks in suspended status in the Forms Monitor. The full stack of the error is shown below. I've searched the Laserfiche knowledgebase and google for the specific error, but have not found any answers.

We are using Forms version 11.

Any idea what would cause this error? The user was able to upload the documents that originally generated this error, so it does not seem to be an issue with the documents.

Hi Robin,

Is this error happens for all instances or just some instances with specific pdf uploaded?

Usually, the error "PDF stream is damaged and it could not be loaded." is because the pdf is damaged so that repository cannot generate pages with text for it.

With Forms 11, there is an option to ignore the generate page error in Save to Repository service task so the process can proceed on.

Hi Yuxuan,

The error occurred only for a handful of documents. The users did not realize that the instances were suspended, so they tried to submit the documents multiple times. One thing that is odd is that several of the documents actually made it into the repository and were filed. In other words, the error occurred intermittently for the same document, which seems to indicate that the document was not damaged.

Thank you for the information regarding the "ignore errors when generating pages" option. We were not aware of this option. Is there any reason that you can think of that we would not want to enable this option?

Hi Robin,

By enabling the "ignore errors when generating pages" option, the process will not suspend when page cannot be generated so the business process can proceed.

Since only several instances failed, we may need more information to investigate the issue. I would suggest to open up a support ticket and our support engineer will help you to investigate further :)

Just to add, this error also occurs when the PDF is password-protected. Needs to be removed as per https://www.adobe.com/za/acrobat/how-to/unlock-pdf.html
