I've run into the ("code":-32700,"message":"Parse error") error when trying to get the altcoin set up for mining. I tried googling around and all the solutions seemed to point to the command syntax/parameters not being formatted correctly but I'm pretty sure my formatting is correct, as the validateaddress returns the expected result when ran manually. Also, echojson (a daemon cli command which parses the given string to JSON) seems to parse the parameters correctly as well. I've been stuck on this for days and I'm not sure what else to do. What could I do to fix this?
Huge thanks in advance!!!
