Running into panic when choose 0 sats to go to myself in zombie channel recovery #158
Description
I'm using chantools to conduct a zombie channel recovery. I am making an offer:
chantools zombierecovery makeoffer --node1_keys preparedkeys-2024-08-25-xxx.json --node2_keys preparedkeys-2024-08-26-xxx.json --feerate 4
I input my keys and am asked "How many sats should go to you (bc1pxxxxx) before fees?:"
I enter 0 and get the following panic:
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x47169a]
