Why Solana RPC write Transaction failed to sanitize accounts offsets correctly?
I tried to copy my token swap transaction. And I get an error:
solana.rpc.core.RPCException: {'code': -32602, 'message': 'invalid transaction: Transaction failed to sanitize accounts offsets correctly'}
Successful Transaction - https://solscan.io/tx/5yL5MnDyLmDGu3xeR4gz8y3pJWGg5qXTzxMgd9qUPgYsPQ5ZUPkJt1DVHkmRAoqZUenHtDqgb4vsfkC1P2vjmKW9
