Connector example NullValueException: Can't find scripting engine for 'javascript'

Camunda 7 Topics Discussion & Questions

I am using Camunda 7.19 and JDK11 and want to switch to JDK17 and have the same problem with Javascript in DMN.
The Camunda Homepage lists under Supported Environments that JDK17 is supported!
So I added dependency to GraalVM as shown in https://forum.camunda.io/t/cant-find-scripting-engine-for-javascript-scriptengine-is-null-camunda-with-spring-boot-microservices/23282/7


        <dependency>
            <groupId>org.graalvm.js</groupId>
            <artifactId>js</artifactId>
            <version>23.0.2</version>
        </dependency>
        <dependency>
            <groupId>org.graalvm.js</groupId>
            <artifactId>js-scriptengine</artifactId>
            <version>23.0.2</version>
        </dependency>

With GraalVM DMN seems to work but following is written to stderr:


stderr: [To redirect Truffle log output to a file use one of the following options:

Can I ignore this messages?
