[Bug]: ValidationError in getBatchFields endpoint due to strict validation of required fields

Description

A ValidationError (400 Bad Request) occurs when attempting to initialize or retrieve fields for a new Batch in the Dashboard. The error is triggered because the getBatchFields endpoint attempts a partial update on the credential-batch collection, but fails to satisfy the required: true constraints of the collection schema.

Environment

• DCC Admin Dashboard Version: v1.0.1
• Payload CMS Version: ^1.13.4
• Database: MongoDB (Replica Set)
• Node Version: v18.12.1

Steps to Reproduce

1. Log in to the Admin Dashboard.
2. Navigate to the Credential Batches collection.
3. Start creating a new Batch (Draft).
4. Trigger the process to map CSV fields (which calls the getBatchFields custom endpoint).
5. The system returns a 400 error with the message: followingFieldsInvalid title, template, emailTemplate.

Technical Analysis

The issue resides in src/endpoints/getBatchFields.ts. The code performs a payload.update operation sending only the csvFields data:

// src/endpoints/getBatchFields.ts
await payload.update({
    collection: 'credential-batch',
    id,
    data: { csvFields: fields }, // <--- Failure point
});
