Aprendiendo MVC, estoy tratando de sembrar mi base de datos con entradas ficticias y sigo recibiendo este error:

 (node:19287) UnhandledPromiseRejectionWarning: Error at Query.run (/Users/joshuaramat/Documents/projects/tech-blog/node_modules/sequelize/lib/dialects/mysql/query.js:52:25) at /Users/joshuaramat/Documents/projects/tech-blog/node_modules/sequelize/lib/sequelize.js:313:28 at processTicksAndRejections (internal/process/task_queues.js:95:5) at async MySQLQueryInterface.bulkInsert (/Users/joshuaramat/Documents/projects/tech-blog/node_modules/sequelize/lib/dialects/abstract/query-interface.js:335:21) at async recursiveBulkCreate (/Users/joshuaramat/Documents/projects/tech-blog/node_modules/sequelize/lib/model.js:1655:25) at async Function.bulkCreate (/Users/joshuaramat/Documents/projects/tech-blog/node_modules/sequelize/lib/model.js:1744:12) at async seedAll (/Users/joshuaramat/Documents/projects/tech-blog/seeds/index.js:14:3) (Use `node --trace-warnings ...` to show where the warning was created) (node:19287) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag `--unhandled-rejections=strict` (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 1) (node:19287) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

el siguiente es el código utilizado para sembrar mis datos:

 const seedUsers = require('./user-seeds'); const seedPosts = require('./post-seeds'); const seedComments = require('./comment-seeds'); const seedVotes = require('./vote-seeds'); const sequelize = require('../config/connection'); const seedAll = async () => { await sequelize.sync({ force: true }); console.log('SEQUELIZE--------------'); await seedUsers(); console.log('USERS--------------'); await seedPosts(); console.log('POSTS--------------'); await seedComments(); console.log('COMMENTS--------------'); await seedVotes(); console.log('VOTES--------------'); process.exit(0); }; seedAll();

El error parece ocurrir después de llamar a la función seedPosts(). ¿Alguien podría ayudar?
