Problem of WalletConnect Metamask: pre-transaction confirmation error

As a developer, you are probably not foreign to Metamask and its role in the management of wallets. In this article, we will immerse ourselves in a problem that could arise when connecting your DAAP (Deputy Access Applications Supplier) via Wallet Connect on mobile devices.

The problem:

When a user starts a transaction on his mobile device using Wallet Connect, the browser sends a request for events to the RPC Metamask server. Unfortunately, this event is not always properly valid, which leads to errors like the one you live with the Json-RPC internal error.

Error message:

The error message provided indicates that there was a problem with the transaction confirmation process. The exact formulation may vary according to your specific experience:

“Json-RPC internal error”

OR

“The validation of the events failed”

Problem resolution phase:

To solve this problem, follow these steps to help and solve the problem:

1. Check the configuration of the wallet connection

Make sure the DAAP configuration is correctly configured in the portfolio connection settings:

• Confirm that you have activated the portfolio on your DAAP.

• Review the `WalletConnect.json” file to make sure it corresponds to the configuration of your DAAP.

2. Check the validation of events **

Check that the validation of events works as expected:

• In Metamask, go to
  settings >
  Work and accessories .

• Select the DAAP used for the Connect portfolio.

3

• If necessary, adjust or add validation rules to ensure that only valid events are received.

When inspecting the responses of events, seek indexes on the problem:

• Check the response of “events” in Devotools browser in the “Events” tab.

4. API calls validation

To make sure that events are sent correctly, check API calls:

• Check the newspapers of the DAAP RPC server to identify all problems with the validation of events.

• If you use a local development test node, perform API tests in a separate environment to isolate this problem.

Additional tips:

• Keep updating Metamask and Daap versions, because the most recent versions can introduce corrections for this specific problem.

• Take into consideration the implementation of additional Journal tools or surveillance to help identify the profound cause of the problem.

Following these steps, you should be able to solve the JSON-RPC internal error and guarantee an experience of connection of the regular wallet on your mobile device.
