command
As a Passionate Ethereum Developer, You Probable Know the Different Commands Avisable In The Command Line Interface (ETH “(Cli). However, Whenever you Try To Create A Gross Transaction Using The JSON-RPC Method”, You May Encounter Unexpected Errors.
The Problem
When Executing the Following JSON-RPC Order:
`Bash
?
”
You Will Receive An Error Response Indicating That You Are Unable To Create A Gross Transaction:
Error: Unknown Error [Ethereum-Ferror 0x …]: No Supplier Found
Debugct and Solutions
To Solve This Problem, Let Us First Understand The Steps Involved in Creating A Gross Transaction on Ethereum. A gross transaction is an autonomous transaction block that can be used to create a new block or update an existing block.

Const Of Application = {
Method: "Createrawtransaction",
Params: [
{Txid}
]]]
};
