Is there anything I need to add in place of dsnin the properties file ? i am using sentry in my project which is not a web based project

Solution

The DSN tells the Sentry SDK which instance of sentry to hit (for example sentry.io) and which project within Sentry the events belong to.

You need to get the DSN from Sentry and add to your project. In Sentry, in the project settings page, you'll see: Client keys (DSN):

You'll then see the DSN like so:

Copy this (the button on the right), and paste on your sentry.properties replacing the placeholder: https://public:private@host:port/1
