Hello @niniinnini, I'm here to assist you with any bugs, questions, or contributions you have for Superset. Let me know how I can help!

The 422 Unprocessable Entity error when querying datasets in Superset can be caused by several issues related to dataset validation and processing. Here are some potential causes:

1. DatasetInvalidError: This occurs when the dataset is considered invalid due to failing custom validations. Specific validations that can trigger this error include issues like non-existent databases, attempts to change databases during updates, duplicate columns or metrics, and invalid owners ^[1].

2. DatasetCreateFailedError: This error happens when there is a failure in creating the dataset, possibly due to incorrect configurations or missing required fields ^[2].

3. DatasetUpdateFailedError: This occurs when there is a failure in updating the dataset, which might be due to invalid data or constraints ^[2].

To resolve this issue, you should check the dataset configurations and ensure that all required fields are correctly set. Additionally, verify that the database and table names are correct and that there are no duplicate columns or metrics. If the error persists, reviewing the server logs for more detailed error messages might provide further insights into the specific validation that is failing.
