Error in production using Nuxt | Heroku

[juniorgarcia]

I got an error while in production (on Heroku) due babel-helper-vue-jsx-merge-props which is required by this component, but not declared in dependencies on package.json. Since Heroku removes the devDependencies, this triggers this error.

Here is the line requiring this dependency.

Info:

Tool	Version
Node	v14.11.0
NPM	6.14.8
Yarn	1.22.5
Nuxt	2.14.5
