I need to get well the hdseed for a pockets in bitcoin-core.
If I create a brand new pockets

cli createwallet mywallet

I assume that bitcoind will generate a random hdseed for it.
However I do not see the way to retrieve that hdseed, there isn’t any gethdseed command.

Based on the documentation of sethdseed (https://developer.bitcoin.org/reference/rpc/sethdseed.html)
I ought to have the ability to retrieve the seed with the dumpwallet command.

The seed worth might be retrieved utilizing the dumpwallet command. It’s the personal key marked hdseed=1

However that does not work, I get an error message if I attempt to dump the pockets secret knowledge.

# cli -rpcwallet=mywallet dumpwallet /tmp/mydump
error code: -4
error message:
Solely legacy wallets are supported by this command

Both the documentation is unsuitable or I compiled with a unsuitable set of flags.
