[erfan132]

Any one can help me?

[erfan132]

Hi again I passed The verify with true but i have this problem in broadcasting transection Mempool accept test failed: 16: mandatory-script-verify-flag-failed (Operation not valid with the current stack size) Any help?

[erfan132]

I sign The transection but it doesn't show in decode

[erfan132]

Nobody |?

bad-txns-inputs-missingorspent indicate you are using outputs that don't exist are you fetching correctly? are you mixing networks?

[erfan132]

No I don't think i get Utxo by this function but Script from this api return in hex as you see its convert from hex to asm but i have this problem i think this related to utxo because sigscript its not completed but im not mix network im really confusing about why this happened it take 3 days on this problem do you have any idea ?

Notice the Final Transection Output the scriptsig is empty, is that the trx after you signed it?

[erfan132]

Yes i think so

[erfan132]

the output of transaction
