Solution 1 (not recommended)

Set NODE_TLS_REJECT_UNAUTHORIZED=0 as env variable
Solution 2

Get certificate from DO dashboard and provide it to knex config
{
  client: 'pg',
  connection: {
    host: process.env.DB_HOST,
    port: process.env.DB_PORT,
    user: process.env.DB_USER,
    password: process.env.DB_PASSWORD,
    database: process.env.DB_NAME,
    charset: process.env.DB_CHARSET,
    ssl: {
      ca: fs.readFileSync(path.join(__dirname, '../ca-certificate.crt'))
    }
  },
  ...
}
