milli-sat payments?

[sw1mclub]

I'm trying to make payments in the milli-sat range, but it seems that a route can't be found to actually perform the payment.

I looked at the query route command and it seems to only accept an amt in sats which makes me think maybe this just hasn't been built out yet?

lnd/cmd/lncli/commands.go

Line 1807 in f7384a0

req := &lnrpc.QueryRoutesRequest{

I'm new to this project so maybe this is an intentional design decision.

Example payment request: lnbcrt120p1psjwgnhpp5wc2t58pr47snxjmekr546nkd4d8eu7tj79uuda9f2n2azwjp22vqdq6dpc85um9wfmxjcm9w3jhxarfvscqzpgxqyz5vqsp5y2dq0ujcw5s9c37l2zdud74rczfa6egpp8hrutc747smxlgxrtsq9qyyssq6wqelx2deu2uqxpj8pvjh2vdcjyz92c47khj77gptkru6cgvtv3rg9sts9j3x0m3cgldjjzxtukwh2yhlm3chxevwj7h7snel38zy4cqec45zf

Example Error:

Nodes can define a minimum amount they are willing to forward. Perhaps there just isn't a route that allows for small payments.
Also make sure you set a non-zero fee_limit, otherwise only "free" routes will be searched, which might not exist in your case.

Thanks! Opening a channel with option openchannel --min_htlc_msat 1 does the trick
