Description

Starting web agent using the following command:

./ignite-web-agent.sh -n localhost:8080 -s https://console.gridgain.com/

Note, that localhost:8080 is specified without the http:// part. It leads to the following exception:

[ERROR][pool-1-thread-1][ClusterListener] WatchTask failed
java.lang.NullPointerException

The localhost:8080 format should either be supported or a reasonable error message should be printed.
