LTC : unable to broadcast transaction

Modified on Sun, 29 Jan 2023 at 10:42 AM

Signing transactions usually requires a privateKey.

However, using the wrong privateKey and or the wrong signatureId (KMS) can cause the following error message:

{
  "statusCode":403,
  "errorCode":"ltc.blockchain.broadcast.error",
  "message":"Unable to broadcast transaction.",
  "cause": "mandatory-script-verify-flag-failed (Operation not valid with the current stack size)"
}

Good to know

When KMS is involved, BTC-based chains require using a key-based signature id.
Mnemonic-based signature id is currently under development.
