Description:
I am running two versions of Nethermind:

Version 1.26.0

Version 1.30.3 or even latest version 1.31.0

When querying transaction details using eth_getTransactionByHash, the response from version 1.30.3 is missing the gasPrice and v fields, while the response from 1.26.0 includes them.

Steps to Reproduce:

1. Run Nethermind node on version 1.30.3.

2. Execute the following curl command:

curl -X POST <MY-RPC-URL> -H "Content-Type: application/json" \
--data '{"jsonrpc":"2.0","method":"eth_getTransactionByHash","params":["0x99893d2faf08db38b1c6ca5fc72c2f1fecf50c36f022ba1fe6363249f34890e3"],"id":1}'

3. Compare the response with the same query on version 1.26.0.

Expected Behavior:

• The response should include gasPrice and v fields, as seen in version 1.26.0.

Actual Behavior:

• gasPrice and v are missing in version 1.30.3. and 1.31.0

Example Response (1.26.0 - Correct):

{
  "jsonrpc": "2.0",
  "result": {
    "gasPrice": "0xea45df12",
    "v": "0x1",
    ...
  },
  "id": 1
}

Example Response (1.30.3 - Incorrect):

{
  "jsonrpc": "2.0",
  "result": {
    ...
   
  },
  "id": 1
}

There is no feild of gasPrice or v

Environment:

• Nethermind Version: 1.30.3

• Sync Mode: Full

• OS: Ubuntu 22.04

Additional Context:

• The issue persists across multiple transactions.

• The nodes are fully synced.

• No relevant error logs observed.

Possible Causes:

• Change in Nethermind's handling of transaction fields.

• RPC output formatting differences between versions.

Suggested Fix:

• Ensure gasPrice and v fields are included in eth_getTransactionByHash responses for backward compatibility.
