  • Hi! 

    We have a problem when we use getpdfflieds on a corrupted PDF. Sometimes our users upload this kind of PDF documents and we don't know how to control it. Would it be possible that this implementation exists in the current plugin and at least the function doesn't fail? It would be enough for us to throw a null. 




    Thank you!

    Hi mikel,
    tbh this will be hard to maintain properly. I mean we are talking for a reason about "corrupted PDF". 
    And if you dont have a valid PDF, how can the function be working on a reasonable level as "PDF tool" function?
    What would be your expected behavior? No error?

    kind regards,
    Richard

    to me more dangerous than helpful. I my personal opinion an alert should be created in a prod environment if a node fails and this is done the best way with an error message and a failed node in a process model instance. If it runs to smooth there is a high chance you miss this behavior, that something was not like it supposed to be. So its in general not the worst way to do it, but i get where are you coming from, I see here rather an issue why there are many cvorrupted PDF files ;)

    Hi, thanks for the reply! Unless there is another way to check in Appian, if there is the PDF is formed correclty, exactly that could be a good behavior.... A null might be fine. A null should mean that the function could not get any fields from the PDF. If the function response is null, it means there is no metadata and should mean that something is going on with that PDF and it is invalid.
