Metamask: Uncaught (in promise) Error: Internal JSON-RPC error. { “code”: -32000, “message”: “Execution reverted”, “data”: “0x” }

Metask error: Unlaid (in presence) Error: Internal Error JSON-RPC

Do you face errors when you interact with a decentralized app (DAPP) built in Ethereum blockchain using Metamans? Specifically, find a message “Json-RPC error”. In this article, we will divide what is happening and provide steps to solve problems and solve the problem.

What is the JSON-RPC error?

JSON-RPC is a protocol used to interact with decentralized applications (DAPPS) in Blockchain Ethereum. It allows developers to send data to smart contracts or interact with them programmed using JavaScript libraries as Metamans.

Metask error: Unaigh (en promise) Error: Internal Error JSON-RPC

Metamask: Uncaught (in promise) Error: Internal JSON-RPC error. {

When you try to call a function of an implanted contract, Metask launches a “JSON-RPC internal error.” This error usually occurs when:

  • The contract code does not accept JSON-RPC.

  • There is a problem with transaction or signature data.

  • The contract has been reversed or interrupted.

Error message that is not captured (in promise)

The error message you provided indicates that there is a problem with the execution of the function of the implemented contract. More accurate:

  • code: -32000

  • Message:” Reversed execution “

  • Date ':“ 0x ”(which suggests a transaction or result of call)

Solving problems in steps

  • Check the contract code : Check that your implemented contract is written in solidity and accepts JSON-RPC. You can check this using Remix IDE, truffle suite or other tools to implement the contract.

  • Check the transaction data : Make sure that all the necessary data (for example,data) are included as a result of the transaction or call. If there is a problem with the signature of the transaction or data structure, it can cause JSON-RPC errors.

  • Check if there is inverted : When a function is called a contract implemented, it can return for different reasons, such as invalid code, insufficient funds or gas limits. Make sure that your contract has enough gas and the function does not have a conditional statement that leads to reversal.

additional tips

  • Use the `console.log ‘method to inspect the transaction data and the result of the call.

  • Try to call a different function of the same contract to exclude specific questions.

  • If you have any problems, consider updating Metask or switching to one last version with improved JSON-RPC support.

By following these steps and problem solving techniques, you will be able to solve your problem. “JSON-RPC internal error when you interact with the contracts implanted in the Blockchain Ethereum using Metask. Happy coding!
