An idea what caused this?

[abemedia]

Will investigate later today. I assume it's a dependency issue or something like that.

[tomkralidis]

Same error here with Jekyll 3.3.1

[lakshmanbasnet]

any solutions found?

[toddstoffer]

I am getting the same error using Jekyll 3.3.1 - @abemedia can you point me to a repo where this is working so I can compare it with my local repo?

[tersor]

I got this too using Jekyll 3.3.1. Fixed by adding jekyll-assets.

Gemfile:

gem 'jekyll-assets'
gem 'jekyll-pdf'

_config.yml:

gems:
  - jekyll-assets
  - jekyll-pdf

[toddstoffer]

@tersor Any chance you could link to the repo that you have this working in? I have added jekyll-assets to the gemfile and config and am still getting the same error as before when I run jekyll build. Also running Jekyll 3.3.1.

[trallard]

Having the same issue (Jekyll 3.3.1) has anyone found a solution?
I also added -jekyll-assets but it did not help

[Pietermachiel]

Same issue here with Jekyll 3.4.1

[bitgal]

same isuue, jekyll 3.4.3

[antgel]

I did what @tersor suggested, it worked, then I ran into Issue #8. :(

Those of you for whom it's not working, make sure you added jekyll-assets to _config.yml.

[shivabhusal]

After I did what @tersor suggested

Gemfile:

gem 'jekyll-assets'
gem 'jekyll-pdf'
_config.yml:

gems:
  - jekyll-assets
  - jekyll-pdf

I ran into this error

jekyll 3.5.0 | Error:  undefined method `data' for nil:NilClass

[TheOddler]

I have the same issue as @shivabhusal

Using jekyll 3.5.1

No fixes? :(

[zhulik]

@shivabhusal @TheOddler it can be fixed by setting existing layout in config for pdf.

[Karakaz]

@zhulik I tried to set it like this but it didn't work..

pdf:
  layout: pdf

Also updated my gems with bundle update. Still getting this

jekyll 3.6.2 | Error:  undefined method `data' for nil:NilClass

[tomstaijen]

bundle resolved this to a very old version of jekyll-assets because some other gem (jekyll-picture-tag) required an older version of fastimage (1.6). Newer versions of jekyll-assets, with try_require, need fastimage ~> 1.8.

So just fix your jekyll-assets version to ~> 2, run bundle install, and see what's conflicting.

[kaiforsyth]

@tomstaijen – this worked for me! Thanks!

[DonLewisFSI]

I had this working until I upgraded to jekyll 3.7.0. Now:

My problem turned out to be with the new version of jekyll-assets (3.0.5). I had also recently upgraded ruby and had to reinstall all the gems since I last used jekyll-pdf. I dropped back to jekyll-assets 2.4.0 and things are now working again. I don't know if the earlier 3.0.x versions of jekyll-assets work.
