Potential indexing issue dropbox

[cmcar827]

Hello,

I am currently unable to manipulate images downloaded from my dropbox without there being an error, either reading as "java.lang.ArrayIndexOutOfBoundsException: 0" or "cannot invoke "java.awt.image.BufferedImage.getWidth()" because "imgInput" is null" once I place the manipulated images into our image software (qupath). I am the only person who is unable to manipulate the images, other members of my team have been able to without issue but I cannot rely on them to process the images for me. I have tried uninstalling the dropbox app on my Mac, but I have also not been able to manipulate images downloaded from dropbox online; I get the same errors. So I am unsure what is wrong with my account. Any thoughts?

Hey @cmcar827 - sorry to hear you're having issues with this.

Just to make sure we're on the same page, could you send us a screenshot of the exact error you're getting?

Also, are the files you're working on online only or available offline on your computer?

Any additional information is more than welcome!

Hi Walter,

Here's a picture of one of the errors, I am currently unable to replicate the other one.

I make the images available online using the dropbox app otherwise they will not open in ImageJ or QuPath, and I download them from dropbox online so they're available on my mac. Neither seem to work.

This process was working perfectly fine for me as of last week; it seems to be a new development.

I see, thanks for the screenshot and the additional information @cmcar827 

Since the error comes from the 3rd party app you're using and not Dropbox, have you tried reaching out to them directly for assistance?

I have reached out to them, but my worry is that it has something to do with dropbox because I am the only person who cannot process the images. Other people with access to the files in dropbox are able to modify them and open them properly, but if I try to access them through my dropbox account they don't work.

Are you able to (pre)view the files normally when you navigate your Dropbox account and when you download them from the web as well @cmcar827?
