Starblocks "unable to find a path to destination"

[ckcollab]

(apologies for spamming issues, but I think people will google these same problems/errors and find the solutions quickly this way!)

I am getting "unable to find a path to destination" when trying to buy something on Starblocks after opening a channel with the faucet:

$ lncli sendpayment --pay_req=lntb12u1pd9csefpp5ptg600r76wsassuk49vhgxrf03wxzjl4tjvfg7hmmwhjge84gt9sdp2xys9xct5da3kx6twv9kk7m3qg3hkccm9ypxxzar5v536rgp9j04ruykkkq8f72d28hn3ukgyk84jfrr0cu7uumvemt3wfsvyj95xqgz2w8ggddqk6ehnp4qe2qd0eqdgp0jrpx85mchzus2kqp9v32mg
{
	"payment_error": "unable to find a path to destination",
	"payment_preimage": "",
	"payment_route": null
}
$ lncli payinvoice lntb12u1pd9csefpp5ptg600r76wsassuk49vhgxrf03wxzjl4tjvfg7hmmwhjge84gt9sdp2xys9xct5da3kx6twv9kk7m3qg3hkccm9ypxxzar5v536rgp9j04ruykkkq8f72d28hn3ukgyk84jfrr0cu7uumvemt3wfsvyj95xqgz2w8ggddqk6ehnp4qe2qd0eqdgp0jrpx85mchzus2kqp9v32mg
{
	"payment_error": "unable to find a path to destination",
	"payment_preimage": "",
	"payment_route": null
}

I may be malforming the payment request/invoice?

Also, here is describegraph output:

Thanks for all the help, so excited I finally have things plugged in (semi) correctly!

EDIT:

Ah, I see in another issue...

Due to a recent change, the channels are only fully advertised after 6 blocks.

I am currently at 5 blocks here, so this could be it...

EDIT #2:

Still seems to not be able to find a path. I opened a channel myself back to the faucet and now my graph has edges:

If your graph is that small for describegraph, then it means that you don't yet have a complete network view. Also, the faucet looses connectivity from starblocks from time to time, they don't directly expose the end node, so at times connectivity is spotty.
