The FormsBridge is in charge of, among other things, removing hidden fields from the JSON representation of the form so they don't get rendered. It seems that you have a form, probably one from a very old Appain version, which is throwing an exception when Appian tries to remove these hidden components.

I suggest you identify what from this is (by trying to reproduce the issue opening the most common forms) and simply open the model in the process modeler, export the form so it gets re-created in the 7.4 format, then re-import it and publish the model so new instances of the model don't show this error.
