Batch Error - Invalid Files

[bbobo]

I occasionally get an exception when uploading a batch "There are invalid files in the uploaded batch." This is an exception that gets applied to the batch in Decipher and seems to happen during image processing. None of the files in the batch are invalid and the batch will even ususally correctly process if I retry. Any idea what triggers this error? 

Thanks!

Hi Ben,

It could be temporary files (often hidden) created when the files are open on a users machine. Are you able to see what documents were read from the folder by Blue Prism?

Thanks

Ben

I don't think it's that because I stepped through the process and confirmed the 'Get Files' action was picking up only the PDFs I wanted to submit. When this happens it sits in 'Image Processing' for 20-30 minutes before throwing that exception.

Here is the error trace pulled from the image processing log:

Hi Ben,

I haven't seen that error before, I recommend raising a support ticket so we can investigate.

Thanks
