NodeJS db-migrate TypeError: Cannot read property '1' of null

Question

I've just installed the nodejs package db-migrate into an existing nodejs project. Everything seems to be configured correctly in regards to the connection to the DB.

Database.json:

{
    "development": "postgres://blabla",
    "production": "postgres://blabla"
}

Migration:

var dbm = global.dbm || require('db-migrate');
var type = dbm.dataType;

exports.up = function(db, callback) {
    db.createTable('users', {
        id: { type: 'int', primaryKey: true, autoIncrement: true },
        username: { type: 'string', unique: true }
        }, callback);
};

exports.down = function(db, callback) {
    db.dropTable('users', callback);
};

Whenever I try to run db-migrate up (with any variation of parameters like specifying the database file, the migration, the number of migrations, etc), the command raises an error every time:

[ERROR] TypeError: Cannot read property '1' of null

I've tried renaming the table, changing the fields, messing with the CRLF line endings, installing different versions of nodejs and db-migrate, etc.

Any ideas?

Answer 1

After about an hour of running in circles I realized the migration was named incorrectly. Its first part only specified the date and not the time. The correct file name format to be used would be yyyyMMddhhmmss-<some text>.

Before (Bad): 20160101-testmigration

After (Good): 20160101000000-testmigration

The error could have been more explicit though...

EDIT:

As pointed out by @2Toad, one has to be careful about what is stored on the folder where migrations are supposed to be found. If you have any *.js file that doesn't follow the naming format, like a helper JS file, the same error will occur.
