<!-- Answer -->
Certainly! Here's a step-by-step guide to help you resolve the 400 Bad
Request error when using the Celery warm-up cache in Superset:
1. **Identify the Endpoint**:
- Ensure you are sending your request to the correct endpoint, which is
`/warm_up_cache`.
2. **Use the Correct HTTP Method**:
- The endpoint requires a PUT request. Make sure your HTTP method is set
to PUT.
3. **Prepare the JSON Payload**:
- Your request body should be a JSON object that matches the
`DatasetCacheWarmUpRequestSchema`. Here's a template:
```json
{
"db_name": "your_database_name", // Required
"table_name": "your_table_name", // Required
"dashboard_id": 123, // Optional, replace with an integer
"extra_filters": "your_filters" // Optional, replace with a string
}
```
4. **Ensure Required Fields are Present**:
- `db_name` and `table_name` are required fields. Make sure they are
included and correctly spelled in your JSON payload.
5. **Validate Data Types**:
- `db_name` and `table_name` should be strings.
- `dashboard_id` should be an integer if provided.
- `extra_filters` should be a string if provided.
6. **Send the Request**:
- Use a tool like `curl`, Postman, or your application code to send the
PUT request with the JSON payload to the `/warm_up_cache` endpoint.
7. **Check for Errors**:
- If you still encounter a 400 error, check the error message returned by
the server. It should indicate which part of the request is invalid.
By following these steps, you should be able to correctly format your
request and resolve the 400 Bad Request error. If you encounter any specific
error messages, they can provide further clues on what might be wrong with your
request.
