error is misleading. It gives the impression that eventIndexStr is optional.
Making it required does not seem to align with EVM implementation, where the user can specify an event index or a filter. Am I missing something?

[silaslenihan]

EVM supports live listening when a tx sig isn't supplied but I decided to leave that out for Solana for now in favor of replay-only which requires the txsig. In the replay path in EVM, index is required as well. I updated the error and comment to be a little more accurate.
