[bug]: Null pointer when closing traproot-assets channel in regtest

[SevenLiquor]

Is the traproot-assets channel available on the regtest network?
When I close a traproot-assets channel on regtest it always causes a node to crash.

environment

litd v0.13.991
unbuntu22.4
regtest

Steps to reproduce

I created two nodes, issued an asset and opened a channel to the traproot-assets. Pay an invoice. When I close the channel, the node receiving the asset closes unexpectedly.

Expected behavior

The channel should close properly and both nodes should be able to settle assets properly.

Actual behavior

The node receiving the asset had a null pointer error and shut down.
