Null LDK routing policy in LND describegraph #4
Description
After opening a channel from LDK to CLN, an LND peer is not always getting the channel update message and applying routing policy to the LDK-CLN channel in its network graph.
It is unclear if LDK is not sending out the routing policy or if LND is not processing it correctly.
Nodes are to send out channel updates after a channel is opened describing their routing policy. The LND describegraph command shows the channels it knows about and the policies from the channel update messages. When there is a LDK-CLN channel that LND knows about, the channel policy for the LDK side is null.
This causes payments from LND -> LDK -> CLN to fail with a RouteNotFound error because it does not know the routing policy of the LDK -> CLN branch.
