Input Parameter Error

Hello!   What does the error message "Cannot get a picture object from the input parameter" mean?   I have a comparison command that takes a picture from a region of a PDF file to be used as ...

    It seems to be working now - I'm not sure why. I believe it was some kind of mapping issue.

     

    This is what I did:

    • I put break points leading up to the "NOCHANGES" command
    • When playback reached the breakpoint, I changed the view settings in the PDF viewer (scaled the view to 100%)
    • The NOCHANGEs line did capture the region and prompted me to update the region capture image
    • This lead me to believe that maybe the settings in the PDF reader had been changed at some point in time or it was updated.
    • I attempted to repeat the process of chaning the view zoom, however the "input parameter failed" error message returned.
    • I stopped trying to change the view zoom and now the checkpoint passes - with warnings:

      "There are several objects that match the identification attributes of the "AVDocumentMainView" mapped object"

    I'm very confused on why it works now.

Might be possible, that there are still elements loading, while you try this.

 

So adding some dynamic wait until successful load might help. (or if there is no way to make it dynamic a fixed time where you are certain that loading will be finished - which makes tests slower, tho)

 

if the answer helped, please consider giving kudos

    I'm with Lagencie  on this.  You're doing a CreateRegionInfo of an Aliased object but you need to make sure that the object exists before you attempt that.  The error message you're reporting seems to indicate that a region is attempted but no region exists.  Try adding a hard-coded delay before this call to make sure.  If that corrects it, considering adding a check with WaitAliasChild before your call to wait for the object to exist before proceeding.
