Error when clicking on the DataSource of my app

Hello, I want to update my DataSource, but when I go under "data" and click on my current DataSource (Swagger), I get this error:

what this could be?

I’m not sure what is causing this error. If you have a Radzen subscription you can send your project to

@enchev what I did is, the file json in Meta/data/, I copied over this file the current Swagger json file for my API, because it wasn't updating by itself!

In case this is wrong, what is the right process when I update my Swagger API (so the swagger JSON changes) and I want to update the models in radzen?
