error code: -4
error message:
This type of wallet does not support this command
Descriptor wallets do not support dumpwallet command.

Use listdescriptors false instead,
you can change the arg to "true" to show the "master private key" instead of the "extended public key" in case you need to derive the address' private key.
But that wont output the addresses directly, you need to derive them using tools or restore it to other wallets.
What are you trying to do exactly? Newly created wallet with large balance... sounds "interesting".

Also, I suggest you to create your own topic to answer that question above, since there seem to be more of it than using that command.
Another note, do not entertain any PMs that you'll receive, keep the non-private conversation public as much as possible.

Hi mpscan have you tried dump with the .txt file
It will work with or without the .txt file extension.
The only difference will be the compatibility of the output with certain txt editor applications.

Thanks for this help.  I run a crypto company and we were migrating our bitcoin core node and created a new wallet. We should have not used this type of wallet, descriptors should have been false when wallet was setup. We moved funds into two addresses on the newly created wallet now we can't get them out.  It is beyond my tech ability mostly and I messed up.  That's the root problem.

I understand keeping everything public -- I have done this for years so 100% sold on that. Are there any open source (read: trusted) utilities that will just let me import this wallet.dat file, read what's in it, and give me a private key for all the addresses with funds or let me move them out?

I'm trying to do exactly this, but I get an error:

C:\Users\xxx\AppData\Roaming\Bitcoin>"C:\Program Files\Bitcoin\daemon\bitcoin-cli" dumpwallet mpscan
error code: -4

It was a brand new wallet created with Bitcoin Core yesterday, I think I used the wrong parameters and made a "descriptor" wallet? I don't know.  All I know is that there is a public address in this .dat that has a ton of bitcoin and I can't get it out and don't have the server it came from anymore. Long ass story. lol
