createpsbt RPC 呼叫不提供 PSBT 輸入和輸出

我正在嘗試使用 RPC 創建 PSBT：

bitcoin-cli createpsbt [[{"txid": "1d76879500aecafde541770b5d44ccec5955b4c1a455fae446bf1df7b5ea43e9", "vout": 0}, {"txid": "e5a8dfa9459ac154fe62652e1d43049dae13f11815da36cc32881e27917a0dff", "vout": 1}], [{"bcrt1qnv3tl3z9cll9faqf79ppfn3rrp7pn9wwmq04p5gqgqtxg55xfxuslkyk94": "0.20000000"}, {"bcrt1qa4h6amsgyc878k094grqh6ktmgvp97dt6et9cy5hjmyxlgd9q63q3p6hch": "1.79900000"}], 0, true]

這是我收到的 PSBT：

cHNidP8BALICAAAAAulD6rX3Hb9G5PpVpMG0VVnszERdC3dB5f3KrgCVh3YdAAAAAAD9/////w16kSceiDLMNtoVGPETrp0EQx0uZWL+VMGaRanfqOUBAAAAAP3///8CAC0xAQAAAAAiACCbIr/ERcf+VPQJ8UIUziMYfBmVztgfUNEAQBZkUoZJuWAOuQoAAAAAIgAg7W+u7ggmD+PZ5aoGC+rL2hgS+avWVlwSl5bIb6GlBqIAAAAAAAAAAAA=

解碼後，PSBT 的inputs和outputs部分為空。為什麼是這樣？比特幣核心應該知道填寫這些部分所需的一切。為什麼不呢？

這是不應該的。createpsbt無法訪問錢包，因此無法填寫任何輸入或輸出資訊。如果你想填寫這些，你可以使用walletcreatefundedpsbt.
