should we decode these values first?

They are already []byte or [32]byte not strings. The issue here is that when inserting them as those types, the DB SDK auto-converts it to base64, all we're doing here is going from []byte to []any to match the JSON-friendly types that are inserted with regular events (comes from parsedJson).

This conversion effectively tells the DB SDK, we want to insert this slice as-is.

"state": uint8(3), // 3 = FAILURE
}

tIndexer.logger.Debugw("About to insert synthetic ExecutionStateChanged event", "executionStateChanged", executionStateChanged)

// normalize keys
executionStateChanged = common.ConvertMapKeysToCamelCase(executionStateChanged).(map[string]any)
