Miner Address always remains 0x00000... in blocks data

[Adeel-trimulabs]

Description

I have made a fully synced polygon node using binaries (heimdall and bor) and use its RPC point to get blockchain,s data.
Trying to get information about miner of blocks in polygon. For this I use web3 methods. All information about block from get_blockByNumber, displays as expected except the miner address, the miner hash should be "the address of the beneficiary to whom the mining rewards were given" (or the address of the block's validator).
0x0000000000000000000000000000000000000000

Polygon node environment

• AWS machine with gp3 storage
• Made fully synced polygon node to use RPC endpoint
  bor version: v0.2.16
heimdall version: v0.2.11
• Branch that causes issue master

Steps to reproduce

• Called get_BlockByNumber from RPC endpoint
• Got this response for block

      }

Expected behavior

I expect that I got miners address as we can see in polyscan that they shows validator of blocks.
It should be like
miner: [0xec20607aa654d823dd01beb8780a44863c57ed07] for block number: 35000222
https://polygonscan.com/block/35000222

Actual behavior

The miner address is always
miner: 0x0000000000000000000000000000000000000000 hence I am unable to figure out who mined that block.

Note

I tried to get the miner from ethereum/go-ethereum#17454 by recovering the pubkey from extra data field in the block headers, I noticed that it doesn't match the record of validator from polyscan
