Script evaluated without error but finished with a false/empty top stack element

Hi everyone,

I’m trying to broadcast a transaction and receiving this response when doing so:

“-26: 16: mandatory-script-verify-flag-failed (Script evaluated without error but finished with a false/empty top stack element)”

This is the transaction decoded:

Check that you are using the correct consensus branch ID. If that is incorrect, it behaves like an invalid signature.
