# Troubleshoot Empty Collection Identifier Error

{% hint style="danger" %}
**At a Glance**: 🚫 An "Empty Collection Identifier" error in Pynt indicates that a collection is missing its identifier, preventing proper recognition during testing. Follow this guide to ensure collections are correctly identified for API security scans.
{% endhint %}

***

## Error: The collection identifier provided in the Pynt configuration under "YOUR-COLLECTION" is malformed.

### What Happened?

Pynt was not able to detect the provided test collection ID.

### How to Resolve?

1. **Verify Collection**: Ensure the collection with the supplied name or ID exists in your workspace.
2. **Check for Whitespace**: Make sure no trailing whitespace (like carriage returns) was added to the collection name or ID.
3. **Save Changes**: Confirm that all changes were saved by clicking the **"Save"** button in the Postman UI.
