Indexing Error: "Cannot read properties of undefined (reading 'hash')" #219

Closed jboetticher closed 2 weeks ago

jboetticher commented 2 months ago

While indexing Axelar events on my local machine, my indexer crashed and would encounter the same error upon restarting. The full error logged is included here:

}

I could not reproduce the error the following day, however it is important to note that this error occurred on chain 250, and chain 250 seems to be lacking a significant amount of data, making me think that the error inducing data has since been skipped.

From a telegram chat:

I mean that hyperindex occasionally seems to skip ahead to the latest blocks instead of indexing from the start. So situations like this, where fantom opera (250) has only 2 events and is at 100% immediately but other chains are still indexing because they start at the actual start of the data.

Though I've noticed this doesn't reliably reproduce every time I start the indexer

JonoPrest commented 1 month ago

Hey @jboetticher, I've just confirmed this due to bugs on HyperSync with fantom network. Unfortunately it's not stable at the moment and it's using an old version of HyperSync.

This, as far as I know, has been fixed. I will close the issue now. If there are issues again in the future, please comment and reopen (or let us know in discord).
