"Error：encoding overruns Uint8Array" when sending transactions?

I tried to compile 2 swaps into one transaction and got this error,

Error：encoding overruns Uint8Array

I know there is a 1232 limit for a single transaction, my question is, is there any way to reduce my instructions size? or is there any other way can make my code works?

const transactionMessage = new TransactionMessage({        payerKey: payer.publicKey,        recentBlockhash: blockhash,        instructions: innerInstructions, // lots of instructions    })    const itemV = new VersionedTransaction(transactionMessage.compileToV0Message())    itemV.sign([...innerSigners, payer]);

Here is code I use. thanx
