Hi,

when upgrading to docusaurus2.0.0-alpha.73 I have a problem when build the docusaurus

the markdown pages of the docs folder:

Docusaurus Node/SSR could not render static page with path=/docs/cadernos/anteriores because of error: Cannot read property 'length' of undefined

https://gitlab.com/unesp-labri/sites/labri/-/tree/main/website

Thanks @slorber, it worked!

Is there a way to better monitor the modifications of the docusaurus blog implementations? If it were possible at least one message indicating this would help a lot

We cost BlogListPage, BlogPostItem, BlogPostPage

We didn't even touch the TOC we brought with the swizzled to see if it would be necessary to customize it too, but it wasn't. Despite this, a modification of the TOC also impacted the BlogPostPage swizzled (right-hand toc)

Especially BlogListPage and BlogPostPage I think are important for people who want to customize the blog

Once again, thank you for your attention and congratulations for your work with docusaurus!

Hi @slorber,

it looks something similar to #3515, doesn't it?

After upgrading to alpha.73, npx docusaurus --version indicates that the upgrade was successful. But when running yarn run build the return is shown below:

rafael@pc:~/codigo/labri/website$ yarn run build
yarn run v1.19.1
$ docusaurus build

[en] Creating an optimized production build...
Warn: `blogDir` doesn't exist: "/home/rafael/codigo/labri/website/blog".

You have swizzled components, which are theme implementation details that we sometimes have to change to evolve the theme, so there's always a risk on upgrades that those components stop working.

When this happens, you can remove all the swizzled comps and try to build the site. If it works, then you now there is an issue with one of your swizzled components,

You can try to restore your swizzled comps one by one until you identify the problematic one.

Once you know which comp has a problem, you can re-swizzle it, and then backport the changes you made to it based on the new implementation.

In this case, the problematic comp looks like the TOC:
https://gitlab.com/unesp-labri/sites/labri/-/blob/main/website/src/theme/TOC/index.js

We have renamed the name of the prop it receives in a recent release, for consistency and clarity.

Thanks @slorber, it worked!

Is there a way to better monitor the modifications of the docusaurus blog implementations? If it were possible at least one message indicating this would help a lot

We cost BlogListPage, BlogPostItem, BlogPostPage

We didn't even touch the TOC we brought with the swizzled to see if it would be necessary to customize it too, but it wasn't. Despite this, a modification of the TOC also impacted the BlogPostPage swizzled (right-hand toc)

Especially BlogListPage and BlogPostPage I think are important for people who want to customize the blog

Once again, thank you for your attention and congratulations for your work with docusaurus!

Those things are the most annoying pain points to solve when implementing custom themes. The whole theme is somehow an implicit API surface on which it is complicated for us to move fast and yet avoid breaking changes. For now you can only check the Changelog for breaking changes. In the future I have some ideas to make this more explicit Le ven. 23 avr. 2021 à 01:21, Rafael de Almeida ***@***.***> a écrit :
