Description

What's going wrong?

pm2 status displays the version of nuxt instead of the application in the version column

How could we reproduce this issue?

Install pm2, deploy an application develop with nuxt (with nuxt build, so it is a production version).
Upon success, run pm2 status

Supporting information

In the report below, the nuxt_app version is 2.5.0, yet nuxt version is shown: 2.14.12.
Both nuxt_app and normal_app have a package.json in their root folder containing the proper version, i.e. 2.5.0.

Research direction

Reproduce the report with the supplied ecosystem configuration, comparing the nuxt_app and normal_app package.json files with their output in pm2 status. Start at the pm2 status version display path and trace how the application directory and package version are selected; done means the Nuxt application's package.json version is shown instead of Nuxt's dependency version.
