Summary

When calling the eth_estimateGas method with a JSON-RPC request that includes both header and data fields, the response returns an error with code -32015 and message "mv". This issue has reoccurred despite using the proper request structure.

Environment

• Nethermind Version: 1.31.4 (latest)
• Endpoint: http://127.0.0.1:8545
• OS/Platform: Ubuntu 24.04
• Additional Context: This is a recurring issue with the eth_estimateGas method even after ensuring the header and data fields are provided correctly.

Reproduction Steps

1. **Execute the following curl command: on sepolia **

   curl --location 'http://127.0.0.1:8545' \
   --header 'Content-Type: application/json' \
   --data '{
       "method": "eth_estimateGas",
       "params": [
         {
           "value": "0x621bfae431e7",
           "from": "0x05d91bb01e437eb185447c1b802197954f060f36",
           "to": "0x32ffec5f06d659a4b2cf9b9a17d381b524f917e0",
           "data": "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"
         }
       ],
       "id": 1,
       "jsonrpc": "2.0"
   }'```
   

Observe the response

{"jsonrpc":"2.0","error":{"code":-32015,"message":"mv"},"id":1}

Expected Behavior

The eth_estimateGas method should process the request and return a valid gas estimate without error.

Actual Behavior

The method returns an error with:

Code: -32015
Message: "mv"

This error occurs even when the proper headers and data fields are included in the request.

Additional Information

I am getting the correct response from public endpoint.
