multi signature – listdescriptors true fails after uploading a 2-of-3 multisig descriptor (prv, pub, pub)

By way of deafult, in a newly created descriptor pockets that’s not watch-only and now not empty, listdescriptors true works and offers output.

Alternatively, here’s a situation that breaks it:

1. Get a brand new deal with within the descriptor pockets.
2. Retrieve its public deal with (pub1)
3. Create a multisig deal with with the usage of this public deal with (pub1) and two others (pub2, pub3)
4. Import the next descriptor into the pockets: sh(multi(priv1,pub2,pub3); I retrieved priv1 from listdescriptors true.
5. Now, if I take a look at listdescriptors true once more, an error is returned:

"error": {
  "code": -4,
  "message": "Can not get descriptor string."
}

Is that this anticipated on account of how I imported a descriptor that combines xprv and pubkeys, or is it a worm?

Word: when uploading this type of descriptor, I were given a caution:

{"luck": true, "warnings": ["Not all private keys provided. Some wallet functionality may return unexpected errors"]}
