Getting a liquid exception after bundle installing octopress-linkblog

[adamstac]

Hey bro, I'm getting this error Liquid Exception: no implicit conversion of nil into String after adding this gem.

I added the gem, added the config details and tried to run Jekyll and get that error on the first post when Jekyll spins up.

Any thoughts on what this might be?

I'm not sure. I'll try to look into it tomorrow. Thanks for the heads up.

Cool. I can help by troubleshooting more on my side too if need be. Let me know, and I'll be glad to help out.

Would this error be related to the switch from Jekyll v2 to v3? I got the same error once I bumped Jekyll to v3:

Hope this helps!

Yeah, just ran into this. Tracing the output gives the following information:

See also: Jekyll #4199 for the fix related to the deprecation warning.

I believe this is the issue fixed by octopress/hooks#14.
