Question

Full error message at the bottom. When running hexo server or hexo generate I'm getting the message TypeError: Cannot convert undefined or null to object. This was working on 4.0.0 but then I updated the package.json to 4.2.0 and it stopped. Reverte to 4.0.0, ran hexo clean, removed the node_modules folder and re-ran yarn install. The error persists after those steps.

Environment & Settings

Node.js & npm version

node v13.5.0
npm 6.13.4
yarn 1.21.1

In my original issue post, I did not include my theme’s _config.yml file because it was empty. However that seems to be the issue. With the added ability to merge the config files there appears to need to be something in the file or it returns the error above.

I had the same error and issue. Added a nonsense setting to the theme’s _config.yml file (it was empty) and the error went away.
