Segfault when using the example code

[Xe]

I have a bot that monitors a subreddit for new posts and posts them to Discord. The source code is here. I am getting a confusing segfault when I try to monitor posts on a subreddit:

$ go run . -subreddit shadowh511
2022/03/08 20:57:44 listening for new posts on /r/shadowh511
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x18 pc=0x73b9df]

I am using graw version v0.0.0-20201204201853-a177df1b5c91 according to my go.mod file, but I am unable to figure out what the problem is. Am I missing something very obvious?

Thanks for looking into this and be well.
