I've looked at similar answers regarding this error, and it seems like the majority of them have to do with using the wrong contract address or the abi. In my case, I do not think this is likely because I am using file saver to update contract addresses every time I redeploy and I am using npx hardhat clean before compiling updates to contracts. I've heard some people point out that this error might be due to missing receive() and fallback() functions. In such a case, what is the logic I should put in the functions? I don't quite understand how they work even after reading up on them.
For context, I'm trying to call a deposit function on js.
This is the error I'm getting:
