Projection goes into a faulted state instantly.

As soon as I try to create a projection I get into a faulted state with this message.

Exception has been thrown by the target of an invocation.

Looking at the logs I see this

I am running the client like this

.\EventStore.ClusterNode.exe --db .\data --log .\logs --ext-http-prefixes=“http://*:2113/” --ext-ip=azure_InternalIP–int-ip=azure_InternalIP --add-interface-prefixes=false --ext-tcp-heartbeat-timeout=10000 --ext-tcp-heartbeat-interval=5000 --run-projections=all

  1. What’s the version of Event Store?

  2. What does your projection look like?

  3. Have you tried a simple projection like

fromStream(’$stats-127.0.0.1:2113’)
.when({
$init:function(s,e){
return { count: 0 }
},
$any: function(s,e){
s.count += 1;
return s;
}
})

``

Just noticed the logs now, so it’s 3.5.0. Ignore question 1. :slight_smile:

Any feedback regarding getting a little more information about this issue? e.g. What does the projection look like? does the simple one I posted work?

Ok I took the simple projection you gave me and it worked. I was trying to use a simple projection that I found on the blog that was not working. I did restart the server between trying that and yours so I am not sure if it was the projection or the restart that worked.

Thanks for your help.
