# Which Problems Are Solved
I noticed that a failure in the projections handlers `reduce` function
(e.g. creating the statement or checking preconditions for the
statement) would not update the `failed_events2` table.
This was due to a wrong error handling, where as long as the
`maxFailureCount` was not reached, the error was returned after updating
the `failed_events2` table, which causes the transaction to be rolled
back and thus losing the update.
# How the Problems Are Solved
Wrap the error into an `executionError`, so the transaction is not
rolled back.
# Additional Changes
none
# Additional Context
- noticed internally
- requires backport to v3.x and v4.x
