Topic: Block failed to accept after changing block header (Read 87 times)

I'm creating an altcoin for research proposal based on bitcoin v0.21. I added two fields to the block header:

1. Address ID (bech32/base58)
2. Signature
Both fields are string type.

I'm creating new blocks by using cpuminer (solo mining). The mining is done by calling submitblock RPC call. During the mining I'm getting the exception: Block decode failed which means that the server cannot deserialize the block.
When I'm printing the exception at DecodehexBlk the error that printed is

Code:

CDataStream::read(): end of data: iostream error

When I'm creating a block by calling generatetoaddress RPC call, the block is accepted to the blockchain.
