[Valexico]

Since recent update, I can't any more create new posts from HTML with API.

Did something change in the package ?

Seems the error comes from https://github.com/TryGhost/Ghost/blob/9150e6776a2fdf7cdd3ad6322840fa13297a4ad0/ghost/core/core/server/lib/mobiledoc.js#L80 . Nothing has changed in package itself. Checking...

Right.. with node 22 it does not load

With node 20, it works fine:

Will pin node in the ghost package - https://git.cloudron.io/packages/ghost-app/-/merge_requests/47
