The **cannot\_be\_served** error occurs when a WhatsApp Flow message cannot be sent or opened by recipients. This issue often stems from incorrect Flow settings, business account restrictions, or missing properties in the Flow JSON.

## What Causes cannot\_be\_served?

The error usually happens due to one of the following reasons:

1. Flow is in an Invalid State – The Flow must be in either DRAFT or PUBLISHED state.

2. Business Account Issues – If the WhatsApp Business Account (WABA) is blocked due to integrity violations, messages cannot be sent.

3. Incorrect Flow JSON Configuration – Missing version or data\_api\_version properties in the Flow JSON file can trigger the error.


## How to Fix the cannot\_be\_served Error

Follow these steps to resolve the issue:

### 1\. Verify Flow State

- Go to Meta Business Manager and check the status of the Flow.

- Ensure it is set to DRAFT or PUBLISHED.


### 2\. Check Business Account Status

- Visit the Business Account Quality page.

- Look for any integrity violations or restrictions.

- Resolve any flagged issues to restore messaging capabilities.


### 3\. Fix Flow JSON Properties

- Open the Flow JSON file.

- Ensure the version and data\_api\_version properties are correctly defined.


Example of a properly formatted JSON snippet:

```
{
  "version": "1.0",
  "data_api_version": "v16.0"
}
```

Save and re-upload the corrected JSON file.

By following these steps, you can troubleshoot and fix the cannot\_be\_served error, ensuring your Flow messages are successfully delivered to recipients. For more troubleshooting tips related to WhatsApp API, check out [heltar.com/blogs](http://heltar.com/blogs).
