I have a local, strapi app (that I have in a git repo) that I want to migrate from using sqlite3 to using mongodb

I have done the following:

  • created a 2nd, temporary, strapi app that is successfully using mongodb from the start (so I have a good mongo instance running locally)

  • copied the database.json content from the temp, working-mongodb, strapi app to my existing one. (made sure was in development and ran development version)

From my existing app (from which I want to use mongodb), I

  • uninstalled:

    • strapi-hook-bookshelf

    • strapi-hook-knex

    • knex

    • sqlite3

  • installed strapi-hook-mongoose

NOTES:

  • the existing app (from which i want to use mongodb) runs successfully if I keep just keep using sqlite3.
  • i created the existing app using the quickstart option

But, I still get this error...terminal output, snippet below

This is cool! I can answer my own question!

Seriously though, I am answering my own question for the benefit of others that might run into the same issue.

Bottom line: I had the wrong version of strapi-hook-mongoose installed.

Details: When I installed strapi-hook-mongoose, I didn't specify a version, and so, npm installed ^3.0.0-alpha.13, and due to the fact that my existing, strapi project is on the (then) latest v3.0.0-beta.7, it failed to run (gave the error described in the above description).

Solution: Uninstall the package and re-install, explicitly specifying the version

npm i strapi-hook-mongoose@3.0.0-beta.7
