Walletwasabi: BUG: PSBT is too large to be signed by wasbai

[nopara73]

"the textbox don't accept enough chars" reported by @NicolasDorier on slack.

@yahiheb @jmacato could one of you take a look at that? Build a large transaction under the advanced wallet tab/ build transaction.

[jmacato]

For some reason, i can't repro this. @NicolasDorier can you give us any repro text to work with?

[NicolasDorier]

sure one sec

I can see 9949 out of 9992 chars in the textbox if I CTRL+A , CTRL+C it seems I copy the whole transaction (9992 chars). If I click "broadcast transaction" it says "Invalid Hex String".

[jmacato]

@NicolasDorier the text being cutoff visually in the TextBox is a known issue (same bug that plagues the Privacy, License, T&C textboxes). I'm not familiar with Transaction Hex's yet but i'll check why it fails.

[jmacato]

I checked the string that is passed to PSBT and it seems that the MultiTextBox control doesn't do anything suspicious on the string.

[jmacato]

@NicolasDorier so i debugged it further and the exceptions are coming from these lines:

[NicolasDorier]

thanks @jmacato . Wasabi try to extract the transaction from PSBT, fails, then fallback trying to parse the base64 as a transaction, fail and show this message..

I think the error message must be fixed, because my string is correct, the PSBT CAN be parsed, but not finalized. The wrong error message + the visual cutoff made me take the wrong assumptions.

A better error message would be "The PSBT can't be finalized"

[jmacato]

@NicolasDorier yes i think that exception should be displayed correctly. But im not sure what was the rationale with not catching specific Exception messages.

[NicolasDorier]

@jmacato I don't think there was rational. Probably @nopara73 did not know that Finalize could throw exception and thus considered that anything throwing exception mean the PSBT is not valid (which is partially true, it is a valid PSBT, but can't be finalized) and thus it should be a Transaction in hex instead. (which is wrong)

[jmacato]

If i parse it correctly, then perhaps it'll be enough if we catch PSBTException then say that the PSBT was not finalized? If it's other exception then perhaps try doing Transaction Hex? Would that work?

[NicolasDorier]

@jmacato yes this would work..

[jmacato]

@NicolasDorier Awesome, will fire up a PR right now :)
