How it’s possible to get (in web3.js for example) the RPC error execution revert message ?
I see on my console that the message is known and I would lik to get it and display it on the UI of my Dapps

Hi @MacFly ,
Have you been able to review the RPC API section of the MetaMask docs here:
digging, but sharing what first comes to mind in case it helps.

Thanks @KBeeTheCapybara but yes i read the RPC API documentation but unfortunatly i didn’t find an answer to my question.
To clarify : I would like to get the revert message (as written in solidity) and display it on the user interface. I can see in the console that the revert message is clearly visible so i think it’s could be possible to have a RPC API function able to get it ?
isn’t it ?
Thanks for your help
Gotcha, thanks for the clarification. I’m working on getting an answer for you.
I found this with something similar in comments…still not exact.

Hi
When we have a revert in a transaction, web3 throws an error, and the erro… r message contains this revert reason.
This error happen because i have a require inside my contract, so it is correct. So, i have a question: I can't get the custom message?
For example, if i have this require below:
` function functionExample( uint256 _number) public returns (bool) {
require(_number>10,"Number need to be bigger than 10");
}`
When i send a number, for example, 8 (<10, so require revert the transaction), and i`m receiving this return:
`{ Error: Transaction has been reverted by the EVM:

"transactionIndex": 2
}`
Is it possible to receive the custom message? I mean, this message: "Number need to be bigger than 10".
This is so crucial for all contracts, and until now, i cant get this value...

Hi @KBeeTheCapybara
Yes it’s the same issue but from what I read, the solution is not found. I would like to be able to display on the front end the message of the reverse reason
