Is there an address associated with P2WSH scripts?
for testnet txid =6717c8971dccbf826790efc16fb357f1e225fed3448247b8556c9f13a6c0ce42, i get: "vout": [ { "value": 0.05994165, "n": 0, "scriptPubKey": { "asm": "0 43aac20a116e09ea4f7914be1c55e4c17aa600b7", "hex": "001443aac20a116e09ea4f7914be1c55e4c17aa600b7", "type": "witness_v0_keyhash" } } ] Is there no address associated with this?

It's a Segwit output and hence does not have the address associated with it. The locking script for a Segwit transaction includes the witness version (0 in this case) and the redeem script (which is 43aac20a116e09ea4f7914be1c55e4c17aa600b7). Given that the length of the redeem script is 20-byte, this locking address is pay-to-witness public key hash (P2WPKH). Hence the redeem script is hash160 of the compressed public key.

Since Segwit was implemented with a soft fork, there are clients that have not fully updated their software. For those clients, the locking script will look in a way that anyone can spend the output. But for Segwit aware clients, they would realize that it is a Segwit transaction with 0 as the witness version.

You could create a pay-to-script-hash of the P2WPKH. By that I mean that you could embed the witness as a script and generate an address. What you need to do is take hash160 of (0x001443aac20a116e09ea4f7914be1c55e4c17aa600b7). The first byte 00 is the witness version, second byte (14) represents the bytes to push to the stack (20-bytes) and the rest is your witness. Then you can base58check encode it using a prefix of '0x05'

In the future it is expected that most clients will upgrade to Segwit. At that time, it is proposed that the address to be locked will be a base32encode of the script (0 43aac20a116e09ea4f7914be1c55e4c17aa600b7). The address will start with bc for mainnet, separated by 1 and then the encoded version including the checksum. This addresses are called Bech-32 address.

This is how the address will look. Refer BIP-173 for more details.

Native segwit outputs (P2WSH and P2WPKH) do not currently have an address type, so there are no addresses for these outputs.
