Resolution of the problems of Ethereum Contract Runner errors *
As a developer, with Ethereum contractors, it is possible to frame the errors of Tinter to your Roundm. In this article, we will explore
The error message:
`Json
{
"Code": not supported_operation,
"Versetto": 6.11.1
}
This error is related to the "Sendtransation" operation, is a chronic function for sending Eterum transactions.
What does error mean?
The error message that the "Ruunner contract", a utility provided by Ethereum to help manage and test the contractor. This MES that you cannot from that page in your contraction.
Why is it happening?
There are several reasons.
- Contractual complexity : your contraction can have a complex logic that requires advanced features, it can be supported by the contractor.
- Discussion of the version : Make sure your contraction and the contract of the contract use the same version. If they are incompatible, you will meet that error.
3
solutions:
To solve this problem, follow these steps:
1. Check the Tuoor contractor code
Review the origin of the contract to make sure that meets the requirements of theSendransation 'operation. If the operation is not necessary for Tuoor's contractor, removal or simplifying it.
2. Update your contraction runner and the Ethereum platform
Make sure you are the last of the contraction meetings that the runner and the Ethereum platform. The numbers are usually possible in the documentation of the contraction or in the Etherum Developer network (eg suite on the truffle).

- Update your configuration of the Ethereum platform (`
ganache.json,.env, etc.) to make sure you are the lact.
3. Check the platform limitations
If you have checked, that the code of your contractor is compatible with the “Sendtransation” operation, it is life. In this case:
- Perform
Eters.js-list-operations and check that no operation is supported by your story (for example,Cals', Etch.).
4. Implement a Fallback function
If you need theSendtransation, it consists in implementing a fallback, that, the default behavior of the contract run. In this way, it is possible to provide a fallback for users without managing the co-controlle.
For example:
`Javascript
Sendransation function () {
triy {
// Use the default behavior of Contract Ruunner.
} Catch (error) {
Console.error ('Error sending the transaction:', error);
return;
}
}
Sendtransation ();
`
Conclusion
If you have the above and print the error, it can be reachable on the Driumen Etherum Developper network for a more specific guide. Remember that the updating of your contraction runner and the Etherum platform is a more impossible solid.
Fallew the problems resolution of the problems, you should be a resolution of the error and continue what with your Etherum contractors.
