Moralis Sync Server catch failed transactions

Hello there! I confused to figure out how using Moralis Sync Server i can catch rejected/failed ERC20 transfer transactions. Should i use some code in cloud functions, filters or etc.Thank you for further help!

That might not be possible, since contract sync is listening for events and if the transaction fails no event is emitted?

In that case what you can do is to watch that particular address that was involved in that transaction, as no event was emitted
