I'm having an issue with Devextreme 19.1.5 sending a blank expand query parameter. This did not happen in 18.2.
Here's an example:
Notice when you click the reload button the app with send a request to the odata service as shown below:
It appears this sample Odata service handles the blank expand condition but my implementation of ASP.NET Odata doesn't handle this. ("'select' and 'expand' cannot be both null or empty.")
Can we get it fixed so the expand condition doesn't go if it's not provided?
