Unknown Error in Stack trace

I am completely lost regarding this stack trace. Anyone have any ideas?

This error means that the PropertyMapper can not find a type converter for a property that should contain an image as value. This can can happen if the data of the node is corrupted, or maybe you did not run all migrations after an import / constructed a node in an incorrect way.

Can you give some more information about when the error occurred? Maybe after an upgrade of Neos or so?

Hey Rens, thanks for your response. There is another developer who is working on the site along with myself, so he made some modifications but I believe it may happened when I was trying to apply the following Aloha patch to facilitate a color picker https://jira.neos.io/browse/NEOS-468

Is there any possible way to revert to NEOS before those patches may have been applied?
