# 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.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.pynt.io/documentation/api-security-testing/pynt-scans-troubleshooting/pynt-for-postman-troubleshooting/troubleshoot-empty-collection-identifier-error.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
