Parse Error 141 on watchEthAddress

what did you see as synced historically?
maybe are some addresses with lots of transactions

EthNFTTransfers has data with a blocktimestamp from April 13th thats how I saw it. Before the collection was empty

yes, but it looks like addresses were added to sync since 6 April

I synced addresses many times but I wiped the EthNFTTransfers collection before I added the new ones now and these show up up with old data now.

it looks like some things were stuck because of that invalid event sync, maybe that is why you see some old data now

alright. I keep an eye on that thank you for the time and help mate. Keep me posted on the unionWith topic please as I am stuck at the development stage due to this. That would be cool
