Hey @techieravishah! I'm here to help you with the issue you're facing. I'm a bot that can assist with bug fixes, answer questions, and guide you on becoming a contributor. Let's tackle this together!
The error message "POST /api/v1/dataset/ HTTP/1.1" 422 indicates a validation issue with the data being sent to create the dataset. The 422 status code means "Unprocessable Entity," which typically points to validation errors in the request payload.
To diagnose and resolve this issue, follow these steps:
-
Ensure Correct JSON Payload: Verify that the JSON payload sent to the
/api/v1/dataset/
endpoint is correctly formatted and contains all required fields. TheDatasetPostSchema
class defines the required fields and their validation rules:class DatasetPostSchema(Schema): database = fields.Integer(required=True) catalog = fields.String(allow_none=True, validate=Length(0, 250)) schema = fields.String(allow_none=True, validate=Length(0, 250)) table_name = fields.String(required=True, allow_none=False, validate=Length(1, 250)) sql = fields.String(allow_none=True) owners = fields.List(fields.Integer()) is_managed_externally = fields.Boolean(allow_none=True, dump_default=False) external_url = fields.String(allow_none=True) normalize_columns = fields.Boolean(load_default=False) always_filter_main_dttm = fields.Boolean(load_default=False)
-
Check Server Logs: Look for detailed error messages in the server logs that might provide more context about why the dataset creation failed.
-
Enable Detailed Logging: To capture more information, enable detailed logging by setting the logger level to
DEBUG
for the relevant module. You can do this by adding the following configuration:import logging # Set the logger for the specific module to DEBUG level logging.getLogger('superset.datasets.api').setLevel(logging.DEBUG)
You can place this configuration in your main application setup or configuration file where the logging is initialized.
-
Known Issues: There are known issues in Superset 4.0.2 related to dataset creation that might cause a
422
error due toDatasetInvalidError
orDatasetCreateFailedError
during the dataset creation process [1].
By following these steps, you should be able to identify and resolve the issue causing the 422
error during dataset creation.
