If I set fallback_to_build_date: true as suggested, it doesn't crash 🙂

Let me know if I should open a separate issue for the second traceback 😄

[pawamoy]

Oh, my config:

plugins:
- git-revision-date-localized:
    enabled: !ENV [DEPLOY, false]
    enable_creation_date: true
    type: timeago

[pawamoy]

Downgrading to 1.3.0 fixes both issues 🙂

[timvink]

Thanks! Will look into it.

[timvink]

Both errors are related to dealing with generated files (that don't have a file.abs_src_path attribute).

Should be fixed in #171 (including a unit test to cover this edge case), released as v1.4.2 to pypi. Can you retry and confirm it works for you also?

[timvink]

Closing, feel free to reopen if there are any issues remaining

[pawamoy]

Working well! Thank you for the super quick fix and the very nice plugin 😄
