    Opening PDF from Drop Box causes and error.

    Asked by jshgambit on May 18, 2011 at 12:34 PM

    I have a JotForm on our Radio Station web site to allow musicians to submit music to us in one unified way. With the addition of the DropBox tie in, I have everything load to my DropBox. PDF's and music files to be exact.

    Well...I was looking through some of my submissions when all of the sudden, every PDF I tried to opened caused an error stating that the file was empty!? See attached screenshot. The size even confirms it.

    Jot Form PDF Error


    Fortunately, I have the emails from the submission with the info in those files, but this was something that worked and is now broken, and I'd like it fix or like to be made aware of any solutions or corrections to issues I'm creating.

    Hi jshgambit

    I'm wondering if it wouldn't be better to specify all the file type extensions, separated by commas, likely to be uploaded (including, of course, pdf) instead of putting an asterisk (to represent the extensions all possible file types).

    Please give it a try and let us know if it resolved the problem.

    Sorry for the confusion, I should've been more specific. My form users aren't uploading PDF's, just audio files at this point. The PDF's in my Drop Box folders are the PDF's created by JotForm after my users complete the form.

    Does that help a little more?

    This looks like an isolated issue. I tested the Jotform's dropbox integration on my own form and I could not replicate your problem.  Also, I have made a test submission on your form, please do check if you're still receiving  an empty pdf in your dropbox account.

    If I remember correctly, there was an issue the other day concerning errors on pdf converted forms.  The issue has been fixed, so it might have been that your pdf entry was affected.

    Anyway, do let us know if this problem still occurs. We'll try to find a solution to this. Thank you.

    Thanks for the test. I did check the JotForm exported PDF in my DropBox folder from your test and it does NOT show and empty PDF. So it looks as though things are back to normal.

    Before I had submitted this issue, I did notice that JotForm had experienced and issue the other day concerning errors on PDF converted forms. Out of curiousity...Did that issue only effect newly exported PDF's, or existing? I believe that some, if not all, of the PDFs that are now "empty" in my DropBox, weren't prior to the other day.

    I've saved the emails from all of my submissions, so at this point I'm not missing any info and I think we can close the case on this for now. If I run into any issues, I will be sure to post again. Is there anything else that would be helpful to you guys, information wise, that I should be sure to include should this issue arise again?


    Thanks again JotForm team!

    Glad to hear that the problem has been fixed. I had a hunch that it was related to the other issue. Since it got fixed yesterday (I think), the problem affecting your dropbox pdfs got fixed as well.

    What's good about this is that there are two more copies of saved information you can rely on, the email and the data in the submissions page.

    If ever this problem occurs again, we would appreciate it if you provide us the link to the form in question and the submission id's or the file name of the pdf entries.
