Running into panic when choose 0 sats to go to myself in zombie channel recovery

[Liongrass]

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]

goroutine 1 [running]:

I also run into this error when entering any other amount than zero.

What version are you using? I think this might have been fixed in the latest one. If not, it would be helpful to get the stack trace from the latest version.

I compiled chantools from the latest master only yesterday. Commit c6ffe382739c7c223ab393f9aa6453a6eadb3261

Ah, okay. Thanks. Can you check if #159 fixes this for you?

[Liongrass]

Yes great, that worked! Thank you!
