`createpsbt` RPC call doesn't provide PSBT inputs & outputs I'm attempting to create a PSBT using RPC:

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


This is the PSBT I receive in return:

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


When decoded, the inputs and outputs sections of the PSBT are empty. Why is this? Bitcoin Core should know everything necessary to fill these sections out. Why doesn't it?

bitcoin-cli -regtest decode &lt;psbt&gt;

It's not supposed to. createpsbt does not have access to the wallet so it cannot fill in any input or output information. If you want those to be filled in, you can use walletcreatefundedpsbt.
