      1. What would you like to communicate to the user about this feature?
      2. Would you like the user to see examples of the syntax and/or executable code and its output?

      Summary

      NET8, I found a problem. Dynamic type of data can not be inserted into the database, but switch the SDK to 7.0 or 6.0, the problem remains. Then I tried to downgrade MongoDriverc from 2.19.0 to 2.18.0 and the problem disappeared.
