Still its showing same error

[aadarsh-nagrath]

Yes @gyan-sy I am facing the same problem in this. I have tried Changing to Sepolia But this is the exact error irritating me. Have you got any solution ?

[harshbaid-13]

@aadarsh-nagrath have you got any solution?

[aadarsh-nagrath]

@aadarsh-nagrath have you got any solution?

Yeah, I did solved all errors and shifted it to Polygon U can check it here -> https://github.com/aadarsh-nagrath/Web3.0_App.git

Client and web3 directory will be useful to you; there is doc ... but I guess you already know how to setup a project.

[AliyaAkhtar]

@aadarsh-nagrath Isn't there any other way of resolving this error. Is it necessary to shift to the polygon. Can't this error be resolved with Goerli

[aadarsh-nagrath]

@aadarsh-nagrath Isn't there any other way of resolving this error. Is it necessary to shift to the polygon. Can't this error be resolved with Goerli

It can be; mine works for all networks. Error needs to be solved. The network can be any regardless.

[AliyaAkhtar]

@aadarsh-nagrath Can you tell me what how you have resolved the error. Following is my index.jsx code.
