Columns [meta] and [type] included in mssql query using holidayextras/jsonapi-server

I am using a jsonapi-server to connect to a mssql (SQL Server Express) instance using a jsonapi-server-relationaldb handler. I have defined a resource for "workers" following the example included in this project and receive the following error when attempting to query rest/workers:

"errors": [
    {
      "status": "500",
      "code": "EUNKNOWN",
      "title": "An unknown error has occured",
      "detail": "Something broke when connecting to the database - Invalid column name 'meta'."
    }
  ]

I've turned on logging to see the raw sequelize query string which is as follows:

SELECT [id], [type], [meta], [first_name], [last_name], [phone_number], [middle_name], [title], [suffix], [email_address], [birth_date], [date_created], [date_modified], [address_line1], [address_line2], [address_line3], [address_line4], [city], [state], [postal_code], [country], [clark_region] FROM [workers] AS [workers];

As you can see in the query, [meta] and [type] are bing included in the query string. What am I doing wrong?

Finally for reference, here is the workers resource model I've created:

const jsonApi = require('../../.')
const workersHandler = require('../handlers/workersHandler.js')

jsonApi.define({
  namespace: 'json:api',
  resource: 'workers',

    username: "rnam",
    password: "administrator",
    logging: console.log
  }),
  searchParams: { },
