Error in broadcasting the transaction

I have an issue with sending the transactions to the zcash testnet which is installed on my local
node.I can’t broadcast the transaction to the zcash testnet. I will give the entire steps clearly. Could anyone tell me where I am doing wrong.This is my zcash address “tmRvLFZ3Lnz9vhd9bG2JuWakYESEi4ukxqs”. Private key - “cSwoLKkeHSj3zaKAqiv8DXKXQVm18Ci3vwTvgrtPAS6a2YJ1HeRY”

output:
error code: -25
error message:

There might be an issue with too large of a fee. First of all set debug=1 in your zcash.conf to get better outputs in the log. Then you can try sending again to see if there’s more information about this error or you can try sending a larger amount which will result in a lower fee to confirm whether this is indeed the issue.
