"error": "Dataset schema is invalid, caused by: QueryContextFactory.create() missing 2 required keyword-only arguments: 'datasource' and 'queries'"

### Bug description

I'm using Superset version 5, and since I started using it, I’ve been seeing the toast message:

“Error loading chart datasources”
(status 422 in the browser console)

This happens every time I create a new dashboard.

From my investigation, it seems this error is caused by a bug during the creation of charts and native filters. In the internal metadata database, I found that some of my charts and filters were missing the datasource and queries fields in their metadata.

I tried manually updating these values (using AI-generated SQL queries), and although the flags changed from `"t"` to `"f"`, the toast message still appears. For a while I just hid the message, but when I try to use the export data API, this error prevents the chart data from being returned.
