Bug: NoMethodError: undefined method `[]' for nil:NilClass

[0xdevalias]

If I wipe my cache folder, and run the below command, it seems to work properly (at least doesn't crash). The 2nd time I run it, I get the following.

I'm also not seeing any actual mentions, even though I am pretty certain there should be (querying webmention.io for my domain using the key shows me a number that don't show up)

I have a test bugfix for this. I’m pushing it to the bugfixes-2017-07-17 branch. Can you the gem from a local source and let me know if this fixes the issue?

Testing that version, seems to no longer get the nil error

Takes an extremely long time to go through though :(

Also, still not seeing any mentions for my URLs in the cache when I know there definitely should be some.

They look like this:

..snip..
"/devalias/2017/03/01/biohacked-box-2/": {}
"/devalias/2017/03/18/iterm-tmux-love/": {}
"/devalias/2017/07/14/link-dump-clearing-out-my-todo-list/": {}
"/devalias/2017/07/16/bugcrowd-levelup-2017/": {}

Is that right? Where/how is it reading the domain/etc?

webmentions:
  username: devalias.net

It should speed up over time.

Is that right?

Yep.

Where/how is it reading the domain/etc?

It pulls the domain from the _config.yml file url value. It also factors in webmentions.legacy_domains.

Cool, I need to do some digging to see exactly what the URL structure of the old mentions was then.
