If you have a problem using the go-ethereum library then you're probably best asking at the tracker or discussion group for that software.
However, the error message seems pretty clear: you're trying to pass a value of type []byte to a function which takes a string. You can convert one to the other, but it has to be requested explicitly: https://go.dev/play/p/67C3mySRegN Note also that your code posted is badly formatted (it's missing line breaks) which means it won't compile. Using go.dev/play/ to make a self-contained program which demonstrates the problem is always a good idea, since it can be edited in-situ to fix.
