How to send eip 1559 txn using web3?

Question

I am sending my txn like this but it is sent as legacy type only

I found the answer to this , so you have to upgrade @ethereumjs/tx and web3 and then have to use class FeeMarketEIP1559Transaction of @ethereumjs/tx to send the transaction with new type. — Shubham Singh, Commented Aug 6, 2021 at 17:00

Did you update your web3 version ?

As you can see on this page you need Web3JS >=1.5.0 : https://github.com/ChainSafe/web3.js/releases

Then your call seems right and you should get back a receipt specifying type: 0x2
