Bitcoin core trying to sign a transaction loaded from psbt file, but getting "could not sign any more inputs" error I am trying to sign a transaction loaded from psbt file, but I'm getting could not sign any more inputs error.
I did it successfully on the first try. However I cannot do it any more now.
I changed my passphrase of bitcoin-core before I did the second try. Does it matter?

Yes. Entering the passphrase in console using walletpassphrase should resolve the issue
