Account Creation in Polygon SDK

I have created a local, permissioned network using SDK. However, when I try to deploy the contracts using truffle, I get this error. I realize this may be related to the invalid account in the “from” field in truffle-config.js, but what options do exist to create a valid account in Polygon SDK generated permissioned networks? thanks


Error: Returned error: the method eth_accounts does not exist/is not available
