Question

i'm trying to send a two seperate swap transaction as one through the help of versioned transactions to solana network and in return i'm getting the error below

SendTransactionError: Transaction  resulted in an error. 
Request is too big.
Catch the `SendTransactionError` and call `getLogs()` on it for full details.

Answer 1

The two transaction are going over the accepted limit of 1232 bytes.

To overcome this limitation,

1. Try using Jito bundles -> https://docs.jito.wtf/lowlatencytxnsend/

2. send the two instructions in separate transactions.

solana docs on transactions -> https://solana.com/docs/core/transactions#key-points
