Javascript Como resolver erro no knex

[Flávio Júnior]

Como faço para resolver o seguinte erro:

Requiring external module ts-node/register
FS-related option specified for migration configuration. This resets migrationSource to default FsMigrations
FS-related option specified for migration configuration. This resets migrationSource to default FsMigrations
migration failed with error: Invalid migration: 01_create_items.ts must have both an up and down function
Error: Invalid migration: 01_create_items.ts must have both an up and down function
    at Migrator._validateMigrationStructure (C:\Users\Jobsfotogrid\Documents\Projetos\server\node_modules\knex\lib\migrate\Migrator.js:437:13)
    at async Promise.all (index 1)

Este erro acima foi resultado de um código que digitei no windows pawerShell:

npx knex migrate:latest --knexfile knexfile.ts  migrate:latest

Para inserir uma tabela dentro do projeto.
