Metamask Ethers.js Supplier’s error: Unconfigurable property “Supplier”

When using Metamask as a supplier of Ethereum from Vue Pinia, several errors may occur to develop the application. One of the common issues is that the “Ersprovider” configuration is not properly configured, which means that the unconfigurable properties error in creating Ethers Signer and Propomist objects.

Problem: unconfigurable property “supplier”

An error message indicates that there is an unconfigurable property called “Supplier” at the “Ersprovider” facility. This is probably due to how the metamask configurates its supplier when it is used with Vue Pinia.

Debugging steps to solve the problem

To solve this problem, follow the following steps:

1. Look at the Metamask configuration

Make sure that the metamask configuration is properly configured and corresponds to the expected format. Check your file “Metamask.jsonin terms of any errors or inconsistency in the supplier's information.





2. Check the ETERSPROVIDER configuration

In the Vue Pinia store, make sure you have correctly configured "Ersprovider" using the "pinia.config.js file:

`Js



Import {Definepinia} from "Pinia";

Import Ethersprovider from "@Metamask/Detect-Ethereum-Provider";

Definepinia ({

  modules: {

    Suppliers: [New ETERSPROVIDER ({{

      Supplier: "

      Network: "Mainnet", // or "WSS" for Websockets

      Accounts: ["Your Accounts"], // List of accounts for use

    })],

  },

});

3. Check the supplier configuration at Vue Pinia

Check if you have correctly configured “Ersprovider” in your Vue Pinia store:

`Js



Import {USE} with "vue-pinia";

Const Mystore = Usedpinia ();

const detectprovider = () => {

  Const providerconfig = {

    Supplier: "

    Network: "Mainnet", // or "WSS" for Websockets

    Accounts: ["Your Accounts"], // List of accounts for use

  };

  Return the new ersprovider ({... providerconfig});

};

Const Mystoreprovider = DetectProvider ();

4. Update of the VUE application

Update your VUE application to properly import “ersprovider” and use it in your store:

`Jsx



Import {Createapp} with "vue";

Import Vuepinia with "Vue-Pinia";

Import Ethersprovider from "@Metamask/Detect-Ethereum-Provider";

const app = createapp ({{

  // ...

  Shops: {

    Mystore: New Piniamistore (),

  },

});

app .use (Ethersprovider, (pinia) => pinia.use (mystoreprovider));

5. Test your application

After updating the VUE application to use “Ersprovider” and correct store configuration, test the application in the programming environment.

Application

By following these steps, you should be able to solve the error of properties not related to the configuration in creating the Ethers Signer objects and suppliers in the Vue Pinia store. Make sure that the metamask configuration fits the expected format and check if you have correctly configured “Ersprovider” in the Vue Pinia store. Happy coding!
