Downloading asset files can take a while, especially if Bynder is under strain or the connection to Bynder is poor. If multiple editors are working in Wagtail at once and happen choose the same (new) asset at around the same time, they unknowingly take part in a little race: The first request to finish downloading the file and saving the object will succeed, but the other will fail with an
IntegrityErrorbecause, by the time it tries to write to the DB, an object with the samebynder_idalready exists.A similar issue can also occur whilst saving the object, because it can take a while to copy the file from memory to media storage (which happens before attempting to save to the database). So, we need to account for
IntegrityErrorbeing raised at that later stage also. And ensure the newly-transferred redundant file is deleted from storage.
