   Is there an existing issue for this?

   Current behaviour

   A non-watch-only wallet allows to import descriptors with partial private keys, eg: a multisig descriptor with one private key and one public key. In case an xpub is imported in any such descriptors whose private key the wallet doesn’t have, then the gethdkeys RPC throws an unhandled error like below when the private keys are requested.

   0    ➜ bitcoincli -named gethdkeys private=true
   1    error code: -1
   2    error message:
   3    map::at:  key not found
   

   Expected behaviour

   The RPC should properly handle the request and not throw.

   Steps to reproduce

   1. Create a non watch only wallet.
   2. Call importdescriptors RPC with partial private keys, eg:

   0[{'desc': 'wsh(multi(2,tprv8ZgxMBicQKsPdaTnUf1FUTUtnupv4pHiwFLsVHPnNHhJtACT3sdj7eMRx1ixLchduVUD4XQzN5qNyZri9NYkrS4kt4tvgyhnW7byhxHzSHw/*,tpubD6NzVbkrYhZ4WzibfNc8tzv6GtMzQ4LnP5YRgM8X5Dia9iPdBdrx3QujdD9fzkwxnGQaBh3q4eFENqJxr8Fzj9bNZhwGndoWJgQQeKTNRWE/*))#m5xlzyqz', 'timestamp': 'now'}]
   

   3. Call gethdkeys RPC.

   0bitcoincli -named gethdkeys private=true
