Hi, I'm trying to start with Solidity and I've done some progress so far but once I want to test functions for my already deployed contract on the BSC, I get this error all the time. I've tried but there's no answer on the internet. I hope someone can help:

Gas estimation errored with the following message (see below). The transaction execution will likely fail. Do you want to force sending?
Returned error: {"jsonrpc":"2.0","error":"execution reverted","id":3270397186799035}
