elements-23.2.2 "bad-txns-in-ne-out, value in != value out" error

[Impa10r]

I could not send an unblinded 2-into-2 raw tx, on v23.2.2+liquidtestnet4. @levantah had a similar issue with blinded outputs. The inputs and outputs were definitely adding up in my case:

Just for record, this is a draft intended to be send to Liquid Dev, but since I am uncovering things on the go, it may be slightly invalid already:

So our findings are that one can not finalize and send Liquid (tested also on the original liquidtestnet) a transaction which is formed from a PSET that spends two previous blinded outputs without sending to two new blinded outputs (or one unblinded) - see example of two blinded sending to two blinded (each of the inputs was comming from a different wallet which does both a sequential and a parallel (later combined before finalizing) walletprocesspsbt) please have a look and let me know if it is intended to work like this (the error messages do not hint that way)

[levantah]

When combining PSBTs I noticed following:

error code: -4
error message:
Transaction has blind inputs belonging to this blinder but does not have outputs to blind

[Impa10r]

Your's is a separate issue. My tx was finalized, but failed to send.
