 If two messages sent by the same chat2 client happen to have the same RLN epoch value, then one of them will be detected as spam and won't be routed (by test fleets in this test setting).
 You'll also see a `ERROR: validation failed` message
 At the time of this tutorial, the epoch duration is set to `10` seconds.
-You can inspect the current epoch value by checking the following [constant variable](https://github.com/waku-org/go-zerokit-rln/blob/main/rln/types.go#L194) in the go-rln codebase.
+You can inspect the current epoch value by checking the following [constant variable](https://github.com/waku-org/go-zerokit-rln/blob/master/rln/types.go#L195) in the go-rln codebase.
