Thank you for the issue.

It would help a lot if you could send that file (or the specific part of the file) so that I can reproduce the error

The trigger for the issue is a multiline value in the frontmatter. In my case this is generated by Decap CMS.

This bug should now be fixed with the new release v0.6.2 :smile:

As always, let me know if everything is working now :+1:

iakdis commented 1 year ago

By the way, version 0.7.0 is out now. Let me know if we can close this issue :+1:

Thanks a lot! I have tested v0.6.2 and the issue is fixed there. There are other exceptions which I still need to investigate, though.
