ExecutionReportEvent from ws_dispatchers.go (with fields that caused issues removed or fixed) We will use the robust definition we discovered during debugging if possible, or just standard string/int/float pointers if unsure. But for now, let's use the one from `ws_dispatchers.go` but be careful. Actually, `ws_dispatchers.go` had `EventType` `json:"e"`. Let's copy it but maybe use `json.Number` or `string` for ambiguous fields if needed. However, the issue before was "number into .e" which was strange. Let's use `interface{}` for potentially varying fields if we want, but better to be strict if possible.
