No. It happens, also for knives (and fake test bombs/firearms).
It seems that the success rate should be around 70% to 80%, in order to discourage terrorist plans. New attacks require new ways, so better not to ruin a new methods (which will alarm security around the world).
In general, I would also not write it on Stack Exchange (or Internet). It could help bad guys to find ways to bypass security.
The security people are regularly tested with fake baggage in own control belt (and they get some statistics about success rate). Reporting will not help further.

Forget about it. This happens all the time.
It's documented that TSA in the US misses ~90% of test devices and there are regular reports of prohibited but otherwise harmless items, knives, firearms passing undetected. This is widely known in the travel community and no cause for concern.
Be happy you got to keep you tomato sauce.
