@Kukks What is your version of c-lightning? the last version on the master branch?

[Kukks]

@Kukks What is your version of c-lightning? the last version on the master branch?

I believe it is 0.9.3

[vincenzopalazzo]

it looks like to be a recursive payment, and @cdecker fixed a couple of bugs in the pay plugin i this new version that will be out soon. It is this also the case?

Maybe upgrade to the new version will fix your problem.

Let wait for the Christian's feedback :)

[rustyrussell]

Yep, this has been fixed (actually was fixed in 0.10.0):

Changelog:

• pay: Payments with an empty route (self-payment) are now aborted. (Prevent pay from accepting a zero-length route (self-payments) #4379)
