I try to set up a CHIA local testnet blockchain. (testnet7)
Could you give me some idea to set up this lib interact with testnet.
Many thanks.
My issue below:

Hmm. Looks like it defaults to mainnet directory. To work around that you could read the file into a buffer and pass that in the config options for cert/key/ca.
