Help on setup safe unomp mining pool

[genius210]

Dear Dev,
I've create a safe mining pool based on unomp.
my pool can get proper block template and submit hashrate, however, when my pool found a block and try to submit block Hex, error message raised and the safed refuse to accept my submit.
I guess SAFE has implemented some extensions that are different from DASH, how can I modify my unomp pool setting or source code?
Error message is as follow:
2018-10-25 12:20:45 ERROR: CheckBlock(): CheckTransaction of 7c8ba87277db3b2723b636841b320a8a4cbbf60389b07ef0aa198a8e5befbae2 failed with block_tx: bad tx version in protocol v1 (code 16)
2018-10-25 12:20:45 ERROR: ProcessNewBlock: AcceptBlock FAILED

And unomp Debug messages shows:
