FindEventNamesForEventID Failed

[yaoyf888]

When parsing block 2200371 in deepbrain chain, FindEventNamesForEventID failed with an error module index 234 out of range. How can I solve this problem?

Usually, when this happens, it means that one of the hardcoded event types is outdated, causing subsequent events to fail while decoding.

One option would be to debug the event parsing and see which is the last event/event field that gets processed, you can do so by logging this - https://github.com/centrifuge/go-substrate-rpc-client/blob/master/types/event_record.go#L541

Alternatively, you can use the recently added event retriever, you can find an example here - https://github.com/centrifuge/go-substrate-rpc-client/blob/master/registry/retriever/event_retriever_live_test.go#L52
