loopd Fails to cancel failed swap

[AhmedMSedeek]

trafficstars

I've been using loopd for a while now through RTL interface, but recently I got too many stuck swaps in "Initiated" state so I digged deeper to find out what is causing this and found that the payment is reported as failed by lnd but loopd fails to close swap causing it to stay stuck

Expected behavior

loopd should close swap after failed payment

Actual behavior

Kindly check the following output of loopd just after restarted

To reproduce

I'm not sure how to reproduce, it just happens from time to time but a lot recently

System information

I'm using Lightning Loop as a standalone application not as part of Lightning Terminal

I'm interacting with Loop Through Ride The Lightning interface

I'm using "loop-windows-amd64-v0.15.0-beta", I downloaded it from releases page

Could not report failure

Don't worry about this, it's just a quick report to the server that we should cancel the swap back faster. It'll still fully cancel in 30 minutes no matter what. Are you still seeing failures to cancel?

If you lookup the swap with loop swapinfo {hash} is it in a final state? If so, everything is fine!
