Sweepoutput command

Hi Dears,

I had a forceclose with pending HTLCS’s. when I run lncli pendingchannels its says for all “blocks_til_maturity”: are negative numbers so they matured already but funds are not sweept.
so I tried to manualy sweep them using lncli sweepoutput but this command is not recognized. Can anybody help how to solve this?

by the way this is the output from the lncli pendingchannels:
“closing_txid”: “a9c786f914f9ffde990e6c1213112701dac9642694f5f3e34c5bacb2420fe435”,
“limbo_balance”: “798456”,
“maturity_height”: 902674,
“blocks_til_maturity”: -125,
“recovered_balance”: “188080”,
“pending_htlcs”: [
{
“incoming”: false,
“amount”: “499065”,
“outpoint”: “79098bb2e7291b6eb8b37eda2d599608f2cbe664ef508ebadfa4c91d45a476af:0”,
“maturity_height”: 902529,
“blocks_til_maturity”: -270,

},
{
“incoming”: false,
“amount”: “299391”,
“outpoint”: “2f6d0b59810eb8c93025392af465b4eac80eee2b63402d64a19ddc970eb79f78:0”,

“blocks_til_maturity”: -270,

}
],
“anchor”: “RECOVERED”
}
],
“waiting_close_channels”:

I see 188,080 has been returned, and you might get an additional 798,456 when the HTLcs expire… hmm, I’m not sure.
