Failing to broadcast - non-mandatory-script-verify-flag (Witness program hash mismatch)

[Arunpandiaraja]

I'm trying to do a text inscription with this reference https://github.com/fboucquez/ordinal-inscription-example-using-bitcoinjs-lib , but running into this issue RPC error: {"code":-26,"message":"non-mandatory-script-verify-flag (Witness program hash mismatch)"} Note: (im using from and to same address, for testing), have added code below and other info to debug and also im using custom signet. any help would be much appreciated

Hey @junderw if u take a look at this, it would be really helpful

[jasonandjay]

The code seems to be fine

I suggest optimizing psbt.finalizeInput(0, customFinalizer) with psbt.finalizeInput(0) first

if it does not work

I suggest providing a code that can be run directly so that I can help you pick food

[jasonandjay]

hello @Arunpandiaraja

Is this problem solved?

[Arunpandiaraja]

Hey @jasonandjay, turns out I was trying to pull a magic trick with only the reveal and forgot to do the commit first! 🤦‍♂️ But once I finally passed the commit output to the reveal, it all worked like a charm! 🎩✨ Thanks for the assist! 😅 So closing this issue.

[liusongjie575]

Can you tell me how you solved it? Where did the specific code change? I am now experiencing the same problem as you. I manually transferred the UTXO number to reveal and then broadcasted it to me through it
