Script pubkey version 1 not supported when debugging taproot transaction in v0.3.20 #121

Closed supertestnet closed 1 year ago

supertestnet commented 1 year ago

I am trying to debug the following testnet taproot transaction:

btcdeb --txin=02000000000101a96370d1e0594fc69149c6bfeb45ac1bad5f3be969efeafb06219c2bd69c42660100000000feffffff024ca40f000000000016001453332c84c9185cae206648ecc04a497f8ef881d0d00700000000000022512089c36412e00beda0b931c7a044cb6e8d149ffba1ec0635b4517b00867e4b395f0247304402203fac08499ad784f208472433944c60f4d45d2b931d3f16a7dbe0304dc4cace8402204c0067b98fa3624ddd8d69369c6096dc75ae5bd7d1f4a1859cd59776d3a9193d012103abbbce21fcddacb0b0701fa41a383c893f2a950e80ff0be405fa5217767d10f373e82400 --tx=020000000001018eba56849eb20c0592a729c8fa414e8f81aae121b551a0fe811699ae868d9c6c0100000000ffffffff01dc050000000000001976a914344a0f48ca150ec2b903817660b9b68b13a6702688ac0340eecf6469196e3d2ab60e8bfba5e9a42a2bd57c76060ff6bf9d6affa3aae6bcd3fcfe768e2414a3d29f6dba54d7622cdf8ace73d3a16baabb3a223838530f31dd2220c1f474fe02a20702320864891a7c5868d150955b6bf2f0e354277e475ae99041ac21c1abababababababababababababababababababababababababababababababab00000000

The txin is actually real, it can be found here: https://blockstream.info/testnet/tx/6c9c8d86ae991681fea051b521e1aa818f4e41fac829a792050cb29e8456ba8e

But when I run the above command, btcdeb complains that the scriptpubkey of the txin is version 1 (i.e. taproot) and that's not supported: 

btcdeb 0.3.20 -- type `btcdeb -h` for start up options
notice: btcdeb has gotten quieter; use --verbose if necessary (this message is temporary)
input tx index = 0; tx input vout = 1; value = 2000
script pub key declared version=1 not supported: script pub key=512089c36412e00beda0b931c7a044cb6e8d149ffba1ec0635b4517b00867e4b395f

That script pubkey is used in vout 1 of the transaction linked above. What am I doing wrong?

The current version of btcdeb is 0.4.22. Try reinstalling it using the README.md info from the last master commit.

This runs on the latest btcdeb code base (although the signature fails, but it looks like it's a placeholder so that should be fine).
