I am getting error messages when trying to serialize or broadcast a transaction. Any help with this would be appreciated.
I get an error when I try serializing a transaction. I do not get the error message when I pass in true or the disableAll flag in as an argument for serialize(). Non of the other flags prevent the error for serialize().
The error message is:
bitcore.ErrorTransactionUnableToVerifySignature:
Unable to verify signature: Unrecognized script kind, or not enough information to execute script.This usually happens when creating a transaction from a serialized transaction
I get three error messages if I pass in true or the disableAll flag as arguments for serialize() and then pass the serialized transaction to broadcast(). These are:
In the console:
bitcore.ErrorTransactionUnableToVerifySignature:
Unable to verify signature: Unrecognized script kind, or not enough information to execute script.This usually happens when creating a transaction from a serialized transaction
The returned err from broadcast():
SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data
The post response from the insight server:
POST https://test-insight.bitpay.com/api/tx/send 400 Bad Request
Response: TX decode failed (code -22)
Both:
Script.Interpreter().verify()
and
transaction.verify()
are evaluating to true.
