Hi

I received this message when I was sending a query to a local canister after authenticating and getting Identity from Inter net Identity. I read that it is due to not having II and canister both running locally? or is it something else?  
If this is right, is there a way to be able to use II and send local requests?

```auto

You have to run II locally. The local replica does not currently know how to accept signatures from mainnet
