I had a similar issue. It seemed to happen when I updated the assembler.

I updated the following packages and it fixed it for me:

npm i @adonisjs/assembler@latest --save-dev
npm i @adonisjs/core@latest --save

If you notice your package.json you can see that you are on a preview release of the core package "@adonisjs/core": "^5.0.4-preview-rc-2.1".

Hope this helped.
