locktime – sendrawtransaction RPC error occurred: "password":-26,"message":"not final" When broadcasting to https://blockstream.info/testnet – Bitcoin Stack Exchange

I’m trying to broadcast this transaction, but I’m getting the following error:

Got sendrawtransaction RPC error: "code":-26,"message":"non-final" 

What does this error message mean?

FYI, this is the deal I wanted to broadcast. Thank you for your support!
