hello @squiddyswap this is a testnet issue, I will suggest you talk with a representative from polygon multichain Developer's live chat support page. POLYGON DEVELOPER'S SUPPORT. Engage in a conversation regarding your issue with the Polygon representative, they will look into the transaction and help you escalate and resolve this issue right away.

squiddyswap commented 1 year ago

@Sisiann Okay will do. Thank you.

I got this error also. do you found any fixes?

squiddyswap commented 1 year ago

@polygomic No fix for this yet. this error shows its face when you are testing with Mumbai and the events blocktracker is set. Don't know when they may fix this. Because, the blockchain will crash after at least a few hours or less.

squiddyswap commented 1 year ago

@polygomic This also may be related to the bridge. I did about 4 deposits on Polygon Mumbai and after that this started occurring.

This was solved in the ethgo library that Edge uses for tracking rootchain blocks, and solution is included in Edge as per 1.0.0 release.

Basically, this error occurred if reorg happened on rootchain, or some unknown error on data gathering.
