Bumping from 0.2.7 to 0.2.8 breaks with Cannot read properties of undefined (reading 'name')

[marcofranssen]

When bumping contentlayer from 0.2.7 to 0.2.8 I get the following error. 0.2.7 just works fine. Running with next 12.2.5 on node 16.

$ yarn dev
yarn run v1.22.19
$ next dev

Thanks for opening this issue. Can you please provide a reproduction repo with instructions how to reproduce the problem you're experiencing? Thank you!

[marcofranssen]

Its a private repo, any suggestions how I can debug it myself? Maybe it is in one of the markdown files that are trying to be processed.

[schickling]

I'd kindly ask you to try to reproduce the problem in a minimal way (ideally in a new repo) that you can share with me. Otherwise it won't be feasible for me to further investigate this given my limited time capacity.

[schickling]

This will be fixed in the upcoming release. You can already use the dev release via 0.2.10-dev.2 in the meanwhile.

[marcofranssen]

Just gave that version a test. This makes it work again with my stuff. Thanks. 🎉

[schickling]

This should be addressed with the 0.3.0 release. 🎉
