Validation for Endpoint URL when creating a dataSource

DataSource Endpoint Validation
Presently, there is no validation for the Endpoint URL during the creation of a dataSource in Dashboards Management. Consequently, it is possible to create a dataSource with an invalid Endpoint URL, as shown below.

Despite repeated attempts to test the connection, error messages related to authentication issues persist, masking the actual problem associated with the Endpoint URL. Also, I was able to create a dataSource with an invalid Endpoint

Describe the solution you'd like

Implementing DataSource Endpoint Validation would significantly improve the user experience. By incorporating this validation, error messages can accurately reflect the cause of failure during dataSource creation, leading to more efficient issue resolution.

Sure, I'll work on this. What I plan to do is to add the same logic of "test connection", to the create data source validation.
