CONTRACT_VALIDATE_ERROR: why TRON refused the transaction
CONTRACT_VALIDATE_ERROR means the network checked the transaction before running it and refused it: the most common reasons are too little TRX for the amount and fees, an address that is not activated, or a fee limit outside the allowed range.
Nothing ran and nothing was charged. Check the sending address below, fix the reason the error names, and send again.

FAQ
Was anything charged?
No. A transaction refused at validation never runs and is never put in a block.
