Thanks Brian and Saurav.

I have checked the Custom Greeting and Setup and Set topics for Greeting and Closing are both active and referring to the correct ones.

I have 'Default Chat Experience' active in my instance.

Also I have tried few other things like - confirmed that virtual.agent user is active and system property com.glide.cs.va.sys_user referring to correct sys_id( tried by making its value '' too)

I have repaired plugin as well but no go..

Thanks

Hello Harshil,

You would need to look at the log files (System Logs > System Log > All) or use the (System Logs > Utilities > Node Log File Browser) whilst you reproduce the issue to determine the errors thrown when the Virtual Agent is loading a blank screen.

However, unfortunately we do not support personal development instances (PDI), nor do we support ML/NLU training on these PDIs, as per KB0996958: Training NLU model displays error on developer/personal instances.

Therefore, you cannot enable NLU for Virtual Agent on a PDI, as this will not work. If you disable NLU for Virtual Agent (Conversational Interfaces > Virtual Agent > General Settings) on your PDI, does that fix this issue?

Regards,

Brian

Thanks Brian.

I have tried to disable the NLU and don't think there is any progress however this is what I am getting in logs.

JavaScript evaluation error on: var queueMetrics = new sn_awa.QueueMetrics(); queueMetrics.calculateCapacityMetrics(); queueMetrics.calculateAverageWaitTime(); Root cause of JavaScriptException: java.lang.IllegalArgumentException : java.lang.IllegalArgumentException: No enum constant com.snc.awa.domain.AlgorithmType.: java.lang.Enum.valueOf(Enum.java:238)

 

Thanks
