With some of the more recent changes the preventative controls add a number of new enum types that need to be reflected in file_events's enums. Effectively this means adding the following (in the case of browser-paste):
incydr.enums.file_events.EventAction.BROWSER_PASTE = "browser-paste"
For those that want to bypass this in the short term, the Enum class validation is perticularly effective. The easiest method to bypass this is to pass an acceptable enum value and then modify it before the query is searched. Something like the following is a hacky solution to the problem.
query = EventQuery(start_date, end_date).equals('event.action', ['file-shared'])
query.groups[1].filters[0].value = "browser-paste"
event_details = client.file_events.v2.search(query)
