bitcoin cli – Unable to generate tackle after importing Taproot multisig descriptor

I’ve 3 wallets that I exploit to create a Taproot multisig pockets. All my work relies on this https://github.com/bitcoin/bitcoin/blob/grasp/doc/multisig-tutorial.md. Listed here are the exterior and inside xpubs for each:

Pockets 1 (exterior + inside xpubs)

[11776e3b/86h/1h/0h]tpubDCTp9moNmiVHK9KS6j6HEyU9duvomZrE87wTNQMkcZktDu89f3yJFATEQovpsT8KwUDWhut5YYd3zNsUYuv6sGHLozsub1AHPoyL7uGW2LT/0/*

Pockets 2 (exterior + inside xpubs)

Pockets 3 (exterior + inside xpubs)

[9f5cbc68/86h/1h/0h]tpubDDQbi15GQjXYxhAysxdEC6VsSFacJ6hgDAJ7oQy4wUs9sfwMQWtcLqLx7GUbBfWyVwUYMEEJtWmxFXmpmjQL8X4cRdgAJ7BcaazuCYq4iCp/0/*

Right here is my descriptor:

external_desc="tr(tpubDCTp9moNmiVHK9KS6j6HEyU9duvomZrE87wTNQMkcZktDu89f3yJFATEQovpsT8KwUDWhut5YYd3zNsUYuv6sGHLozsub1AHPoyL7uGW2LT/1/*,sortedmulti_a(2,tpubDCTp9moNmiVHK9KS6j6HEyU9duvomZrE87wTNQMkcZktDu89f3yJFATEQovpsT8KwUDWhut5YYd3zNsUYuv6sGHLozsub1AHPoyL7uGW2LT/0/*,tpubDCqr5GVKeptzMG5QKLu1aQKXFXgF6kMy9dYDQ6Nap6emZ3iziMCeVX1pPjEzA7nTmyZS9NP2KjUsGtEs8jNqFcUTpKxAwXPB3yfbee4RthM/0/*,tpubDDQbi15GQjXYxhAysxdEC6VsSFacJ6hgDAJ7oQy4wUs9sfwMQWtcLqLx7GUbBfWyVwUYMEEJtWmxFXmpmjQL8X4cRdgAJ7BcaazuCYq4iCp/0/*))#546p4cqh"

For the primary argument of tr I exploit the interior xpub of pockets 1, and I exploit sortedmulti_a to configure my 2-3 utilizing the exterior ones. The I name the getdescriptorinfo command:

 ./construct/src/bitcoin-cli -signet getdescriptorinfo $external_desc
{
  "descriptor": "tr(tpubDCTp9moNmiVHK9KS6j6HEyU9duvomZrE87wTNQMkcZktDu89f3yJFATEQovpsT8KwUDWhut5YYd3zNsUYuv6sGHLozsub1AHPoyL7uGW2LT/1/*,sortedmulti_a(2,tpubDCTp9moNmiVHK9KS6j6HEyU9duvomZrE87wTNQMkcZktDu89f3yJFATEQovpsT8KwUDWhut5YYd3zNsUYuv6sGHLozsub1AHPoyL7uGW2LT/0/*,tpubDCqr5GVKeptzMG5QKLu1aQKXFXgF6kMy9dYDQ6Nap6emZ3iziMCeVX1pPjEzA7nTmyZS9NP2KjUsGtEs8jNqFcUTpKxAwXPB3yfbee4RthM/0/*,tpubDDQbi15GQjXYxhAysxdEC6VsSFacJ6hgDAJ7oQy4wUs9sfwMQWtcLqLx7GUbBfWyVwUYMEEJtWmxFXmpmjQL8X4cRdgAJ7BcaazuCYq4iCp/0/*))#546p4cqh",
  "checksum": "546p4cqh",
  "isrange": true,
  "issolvable": true,
  "hasprivatekeys": false
}

And I exploit that descriptor to construct the descriptor JSON used to import it into my pockets.
That is what I used to create the json:

external_desc_sum=$(./construct/src/bitcoin-cli -signet getdescriptorinfo $external_desc | jq '.descriptor')
multisig_ext_desc="[{"desc": $external_desc_sum, "timestamp": "now"}]"

After that, I name the importdescriptors technique on a brand new clean pockets:

./construct/src/bitcoin-cli -signet -named createwallet wallet_name="multi_tr" disable_private_keys=true clean=true
./construct/src/bitcoin-cli -signet -rpcwallet="multi_tr" importdescriptors "$multisig_ext_desc"
./construct/src/bitcoin-cli -signet -rpcwallet="multi_tr" getwalletinfo

The response of the import descriptors is:

{
  "title": "multi_tr"
}
[
  {
    "success": true,
    "warnings": [
      "Range not given, using default keypool range"
    ]
  }
]

And the output of get pockets information is:

{
  "walletname": "multi_tr",
  "walletversion": 169900,
  "format": "sqlite",
  "stability": 0.00000000,
  "unconfirmed_balance": 0.00000000,
  "immature_balance": 0.00000000,
  "txcount": 0,
  "keypoolsize": 0,
  "keypoolsize_hd_internal": 0,
  "paytxfee": 0.00000000,
  "private_keys_enabled": false,
  "avoid_reuse": false,
  "scanning": false,
  "descriptors": true,
  "external_signer": false,
  "clean": true,
  "birthtime": 1739107662,
  "lastprocessedblock": {
    "hash": "0000005ba71046c3e13011955cf5a65c09fc7e945030a3d623dbfef8e7b3dce6",
    "peak": 234655
  }
}

After seeing this output I used to be excited and I wished to generate a brand new tackle to funds my multisig pockets, however I received an error:

./construct/src/bitcoin-cli  -signet -rpcwallet="multi_tr" getnewaddress
error code: -4
error message:
Error: This pockets has no accessible keys

After on the lookout for alternate options, I discovered that the deriveaddresses technique works for my use case and I used to be capable of retrieve some addresses:

./construct/src/bitcoin-cli  -signet deriveaddresses "tr(tpubDCTp9moNmiVHK9KS6j6HEyU9duvomZrE87wTNQMkcZktDu89f3yJFATEQovpsT8KwUDWhut5YYd3zNsUYuv6sGHLozsub1AHPoyL7uGW2LT/1/*,sortedmulti_a(2,tpubDCTp9moNmiVHK9KS6j6HEyU9duvomZrE87wTNQMkcZktDu89f3yJFATEQovpsT8KwUDWhut5YYd3zNsUYuv6sGHLozsub1AHPoyL7uGW2LT/0/*,tpubDCqr5GVKeptzMG5QKLu1aQKXFXgF6kMy9dYDQ6Nap6emZ3iziMCeVX1pPjEzA7nTmyZS9NP2KjUsGtEs8jNqFcUTpKxAwXPB3yfbee4RthM/0/*,tpubDDQbi15GQjXYxhAysxdEC6VsSFacJ6hgDAJ7oQy4wUs9sfwMQWtcLqLx7GUbBfWyVwUYMEEJtWmxFXmpmjQL8X4cRdgAJ7BcaazuCYq4iCp/0/*))#546p4cqh" "[0,2]"

  "tb1pk3nj9xt2aempeys63etmw3zfkj8pya0sr2lcl2spf6xqtjev8zfqkfzg5p"
]

my questions are:

Why the primary technique to generatenewaddress isn’t working?
Is the deriveaddresses technique advisable for common use? In that case, I feel I might want to save the used vary to generate new addresses each time (as a result of utilizing the identical vary twice generates the identical addresses). So if I exploit the vary [0,0], the subsequent time I might want to use [1,1] and so forth.

Thanks
