Can't find scripting engine for 'javascript': scriptEngine is null

[Balaji Balasubramanian]

I Guys,

I am a newbie... my environment is

Java version :   JDK 1.8 with scala

Camunda version :  7.3.0

camunda-bom       

camunda-engine    

camunda-engine-plugin-spin   

camunda-engine-plugin-connect

camunda-connect-http-client"        -       "1.0.1",

 

When I try to star process instance

val processInstance =  runtimeService.startProcessInstanceByKey("HATExtensionCall")

I get the following exception. Please  correct me where I am doing mistake or did i missed any libraries. I spent days and got stuckup.

Note : I am using  camunda-bom   import

Please do let me know if you need my code.

issue resolved., 

 changed the ouputparameter to 

 <camunda:outputParameter name="isHoliday">${JSON(response)}</camunda:outputParameter>

and added a missing dependency 

"org.camunda.spin" % "camunda-spin-dataformat-json-jackson" % "1.1.0"

its working fine now. I get response data in my delegate.

Hi BalaB,

which JDK vendor do you use? Oracle JDK, OpenJDK, Apple JDK?

Cheers,

Sebastian
