Unable to complete Call Microservice tutorial sample

[aabuabdou]

Hello,

I have followed the tutorial step by step and when I was running the "Call Microservice" process from the web modeler and also the io.camunda.getstarted.tutorial.Worker spring application on JAVA 17, I get the following exception:

2024-05-21T07:04:36.530+03:00 WARN 36952 --- [pool-3-thread-1] io.camunda.zeebe.client.job.worker : Worker worker#orchestrateSomething failed to handle job with key 2251799814493507 of type orchestrate-something, sending fail command to broker

Anything I am missing here?

Thanks for flagging @aabuabdou, I'm looking into this.

@aabuabdou

It‘s will be about the compiler, spring zeebe provides you with a section about it: https://github.com/camunda-community-hub/spring-zeebe Your compiler needs the arg -parameters enabled

There are snippets on how to configure the compiler: Maven

<build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <configuration>
          <compilerArgs>
            <arg>-parameters</arg>
          </compilerArgs>
        </configuration>
      </plugin>
    </plugins>
  </build>

Gradle:

tasks.withType(JavaCompile) {
    options.compilerArgs << '-parameters'
}

In IntelliJ: Settings > Build, Execution, Deployment > Compiler > Java Compiler
