Ethereum Operation Return Error: “The transaction is returned to call the book hall () Function
As a creator who uses an intellectual contract using an Ethereum virtual machine (EVM), you may have encountered problems with the return of surgery. In this article, we will go deeper why there was an error and how to prevent it.
Question
In your case, by calling the book () a function of your contract, EVM faces the return of the operation. This means that the implementation of the smart contract code has been suspended due to the confirmation failure or other logic error.
Information on error
To prevent this problem, you can access surgery information via eth.gettransactionrecypt () from the EVM console. Here is a fragment from your installation scenario:
`JavaScript
Contract = new Web3.eth.conrat (
‘0x’ + [… Your contractual activity],
[… Your Kontraractabi],
{gas: 200000, args: [… yourgs]}
);
`
In this example, Eth.GettransactionRecypt () Call sets an operative receipt associated with the latest blockchain block. You can check the surgery information below to determine the error.
Details of the operation
After reviewing the operation, you should see an error message indicating the reason for the repayment. In this case, the error may seem like this:
`
0x … (Operations bags)
Error: Returned: The Book Hall Function was not found
`
The “Feature” error report indicates that the contract code tried to call the feature called “Boocroom ().
Solution
To solve this problem, you need to make sure that your contract has a properly defined function of Bookoom (). Here are some possible solutions:
- If the name or parameters of the function have changed, both updates both.
- Use a code analyzer, such as a built -in truffle, to catch possible errors.

Check the logic of the contract : Make sure the Bookoom () function is properly implemented and held as expected. If the issue remains, continue to investigate the logic of the contract.
Solution example
To prevent the problem, you can modify the installation scenario to include a combination statement:
`JavaScript
Contract = new Web3.eth.conrat (
‘0x’ + [… Your contractual activity],
[… Your Contracabi],
{gas: 200000, args: [… yourgs]}
);
Console.log (‘Operation:’, contract.transactionhash);
`
This will see the surgery bags associated with the latest block. After this information check, you can check whether the “Book Hall () function is correctly defined and called the function as intended.
When performing these steps and using the EVM console to check the surgery information, you should be able to identify and solve the problem that “surgery is returned by calling the book hall ().
