RELIANCE26AUGFUT is an active futures contract. You can directly use the Historical Data API with the contract's instrument token and the required intraday interval (for example, minute). The continuous=1 parameter is not required for active contracts. The continuous=1 parameter is applicable only for day-level historical data of expired futures contracts and does not support intraday intervals. If you require continuous intraday data across contract expires, you will need to capture and store the data yourself while each contract is active using the WebSocket. You can refer to similar discussion here.
