Error warming up cache!

The "HTTP Error 400: BAD REQUEST" when trying to warm up the cache in Superset using the fetch_url function could be due to several reasons:

1. Incorrect or Missing Headers: Ensure that the necessary headers, particularly the CSRF token and the Referer header, are correctly set. The CSRF token is crucial for the request to be accepted by the server. If the request is over HTTPS, the Referer header should also be correctly set ^[1].

2. Malformed Request Body: The request body must conform to the expected schema. If the request body is malformed or missing required fields, it can lead to a 400 error. Ensure that the JSON payload matches the expected structure for the warm_up_cache endpoint ^[1].

3. CSRF Token Fetching: Verify that the CSRF token is being correctly fetched from the /api/v1/security/csrf_token/ endpoint and included in the headers for the request. The function fetch_csrf_token is responsible for this operation ^[2].

Check these aspects to resolve the "BAD REQUEST" error.

@dosu,
I only have helm chart to update; how to proceed?

[dosubot[bot]]

To update using only a Helm chart, you can follow the automated release process using a GitHub Actions workflow. Here are the steps:

1. Trigger the Workflow: This can be done by pushing to the "master" branch or any branch matching the pattern "[0-9].[0-9]*", or manually via workflow_dispatch.

2. Checkout Code: The workflow will check out the code from the specified branch, tag, or commit SHA.

3. Configure Git: Set up Git with the actor's name and email.

4. Install Helm: Use the azure/setup-helm@v4 action to install Helm version 3.5.4.

5. Add Repository Dependency: Add the Bitnami repository as a dependency using helm repo add.

6. Create a Unique Branch: Generate a unique branch name for the release based on the current commit SHA.

7. Recreate Branch from gh-pages: Force recreate a branch from the 'gh-pages' branch to ensure a clean working directory.

8. Run Chart Releaser: Use the custom chart-releaser-action to package and release the Helm charts to the specified branch.

9. Open Pull Request: Use actions/github-script@v7 to open a pull request for the new branch against the 'gh-pages' branch.

These steps will help you update and release your Helm chart using the automated workflow ^[1].

The "HTTP Error 400: BAD REQUEST" in the fetch_url function can be caused by several issues:

1. Incorrect or Missing Headers: Ensure that all required headers are correctly set. This includes the X-CSRF-Token, Content-Type, and Cookie headers. The Referer header should also be included if the URL is secure ^[1].

2. Malformed Request Body: Verify that the request body is correctly formatted and matches the expected schema for the warm_up_cache endpoint. Any deviation from the expected structure can result in a 400 error.

3. CSRF Token Issues: Make sure the CSRF token is being correctly fetched and included in the request headers. The fetch_csrf_token function is responsible for obtaining this token ^[2].

Check these areas to resolve the "BAD REQUEST" error. If the issue persists, reviewing the server logs for more detailed error messages might provide additional insights.
