Bug description

We are trying to implement automation of export of dashboards from one superset installation to another and have written code snippets in the two files in attached zip file:

export.zip

When we try to run python export_assets.py we are getting following error:

requests.exceptions.HTTPError: 422 Client Error: UNPROCESSABLE ENTITY for url:

How to reproduce the bug

activate python virtual environment for superset in a putty session after logging as superset installation user.

copy both files in zip file to the above putty session.

run python export_assets.py

The requests.exceptions.HTTPError: 422 Client Error: UNPROCESSABLE ENTITY error typically indicates that the server understands the content type of the request entity but was unable to process the contained instructions. Here are steps to troubleshoot and resolve this issue:

1. Check for Invalid Data: Ensure that all the assets being exported do not contain any invalid or incomplete data, such as missing fields or incorrect data types.

2. Validate Exported Data: Add validation steps to ensure that the data conforms to the expected schema before sending it to the server.

3. Debugging: Add logging to the script to identify which specific asset is causing the issue. For example:

   import logging
   
   # Configure logging
   logging.basicConfig(level=logging.DEBUG)
   logger = logging.getLogger(__name__)
   
   class ExportAssetsCommand(BaseCommand):
       def run(self) -> Iterator[tuple[str, Callable[[], str]]]:
           metadata = {
               "version": EXPORT_VERSION,
               "type": "assets",
               "timestamp": datetime.now(tz=timezone.utc).isoformat(),
           }
           yield METADATA_FILE_NAME, lambda: yaml.safe_dump(metadata, sort_keys=False)
           seen = {METADATA_FILE_NAME}
   
           commands = [
               ExportDatabasesCommand,
               ExportDatasetsCommand,
               ExportChartsCommand,
               ExportDashboardsCommand,
               ExportSavedQueriesCommand,
           ]
           for command in commands:
               ids = [model.id for model in command.dao.find_all()]
               for file_name, file_content in command(ids, export_related=False).run():
                   if file_name not in seen:
                       logger.debug(f"Exporting {file_name}")
                       yield file_name, file_content
                       seen.add(file_name)
   
       def validate(self) -> None:
           pass
   

4. Inspect Server-Side Logs: If the issue persists, check the server-side logs for more details on why the server is rejecting the request.

5. Ensure Correct JSON Formatting: Specifically for exporting dashboards, ensure that the position_json and json_metadata fields are correctly formatted as JSON. Invalid JSON in these fields can lead to the 422 error.

By following these steps, you should be able to identify and resolve the issue causing the 422 error.

There's been no response here, corroboration, or bot feedback in nearly a year, so I'll close this as stale. If it's still relevant in 4.1.1 or newer, we can certainly revisit/reopen.
