An error occurred at element fuSovContact (FlowRecordUpdate).
UPDATE --- UPDATE FAILED --- ERRORS : (ALL_OR_NONE_OPERATION_ROLLED_BACK) Record rolled back because not all records were valid and the request was using AllOrNone header --- for SFDC record with ID :

Autolaunched Flow causing error I am unable to identify a pattern...

Consider the following use case:
When you put a case into a "resolved" status a time-based workflow fires and closes the case after 7 days.
When a case closes an email is sent to the contact, at the same time the contact is updated indicating the last time they were surveyed (eg. at case closure).
ProcessBuilder (detects a change in the case, eg it is closed) and Flow handles the email sending and contact update.

It would seem that the bulkification of Flow is not handling this situation correctly and throws the above mentioned error for no detectable reason.
------------------------------------------------------------------------------------------------------

Consider a simplified Process Builder + Flow created in a pretty bare development org:
ProcessBuilder calls flow everytime a case is updated.
Flow takes the case as input, looks up the contact associated with the case and updates the contact, setting a date/time field.  
(I am guessing the objects involved are not important, but the manner in which the bulkification occurs in salesforce when processing flow is...)


Consider the following data, rows 1-23.  These are cases that when updated will trigger the flow and recreate the exception scenario.  When I say "updated" I mean simply doing an update on the Case Id column to get the flow to fire and not actually changing any data...

Update rows 1-20 = success.
Update rows 1-21 = failure.
Update rows 1-19, 21 = success.
Update rows 1-20, 22 = success.
Update rows 1-20, 22, 23 = failure.
Update rows 1-20, 23 = success.
