I’m trying to add some data to my BDAdaptor class through the application.properties, but i don’t know why but the data doesnt add to my variables and I get an null variables that gives me an error that says the variable “dbName” is null.

there are two spring boot projects, one is monitoring project and other is user project, so in monitoring project i have used inceptor to monitor in user api’s response time and api endpoint etc and i am able to see the response in console with system.out.println but it is not saving into h2 database, while if i hit the get endpoint in monitoring project , it is monitoring those api’s and saving in h2 database but not saving the user project api’s endpoints.
