>SOLUTION

The tip is in this line (red):

Error: Cannot find module 'M:\work\devcli_\javascript\jstopics\express\node_sequelize_ultering_ml40643\prj\node_modules\sequelize\types'

that means the class loader was not able to find a reference.

Check the require statements that contain the type.

In this example, it was found the mistake in this declaration:

const { Utils } = require('sequelize/types');
