given community name is not valid (when trying to list "unmoderated" tag)

So like getting this: https://blog.openhive.network/trending/introduceyourself

returns with:
Error fetching community: WaxChainApiError [WaxError]: Invalid response from API: {"error":{"code":-32602,"data":"given community name is not valid","message":"Invalid parameters"},"id":1,"jsonrpc":"2.0"}: "{"error":{"code":-32602,"data":"given community name is not valid","message":"Invalid parameters"},"id":1,"jsonrpc":"2.0"}"

It's from wax, but it's very obvious that this is not name of the community, so it shouldn't be even called

Similar problem is with case like this: https://blog.openhive.network/somerandomword/anotherrandomword

why it's even processed in a way that it result in calling API? simple regexp can tell that there's no such valid route, apparently, the root cause is that the routing is broken
