As you can see, one of the inputs has been removed from the signed transaction causing the tx to be invalid.

@anon-real I haven’t looked into it yet since there have been other issues that needed resolving first that were also easier to reproduce.

I can share the version of the auction house which is using the dapp connector to place bids.

That would help, as otherwise I’m not sure where to start in reproducing it, as the behavior of signing the P2S while ignoring the regular P2PK one is really weird. We had a problem of it removing the P2S inputs but that was resolved in #2081. Due to some issues relating to upgrading sigma-rust from 0.7.0 to 0.10.0 that we found after it was merged, it was not included in any official releases but it’s tagged for 4.6.0 along with the other fixes I’ve been working on this week. But that’s the opposite of this problem…

Currently (in develop as of that #2081 PR) we shouldn’t be filtering any inputs that we aren’t able to sign for some reason, but the problem still exists for non-owned data inputs, but that will be fixed soon-ish. I plan on starting on this early next week. That auction house would be of help so I can reproduce this myself since just by looking at it I’m unsure of what the problem is.
