BpmnError and Displaying Exception description

Hi Nele

Yes I did, it shows an error has occurred, I have attached the model below.

The way I’m throwing the BpmnError is inside the logic, so will make a webclient call if that throws an exception, I’ll catch it and subsequently trigger the BpmnError. I use postman as I have created an endpoint that initiate the process and thereon delegate and service layer handle the logic.

Delegate Logic:

public void create(DelegateExecution execution) {
    oneService.create(execution);
}

Service Logic:

public void create(DelegateExecution execution) throws Exception {
    this.microserviceDiscovery.setServiceId(ID);
    this.microserviceDiscovery.setEndpoint(ENDPOINT);
    this.webClient.mutate().baseUrl(BASE_URL);

    try {
        FinalClassDTO responseEntity = webClient
            .post()
            .uri(microserviceDiscovery.getUrl())
            .attributes(oauth2AuthorizedClient())
            .accept(MediaType.APPLICATION_JSON)
            .contentType(MediaType.APPLICATION_JSON)
            .body(BodyInserters.fromValue(CamundaVariableHandler.getObjectDTO(execution)))
            .retrieve()
            .bodyToMono(FinalClassDTO.class)
            .block();

        CamundaVariableHandler.setFinalClassDTO(execution, responseEntity);
    } catch (RuntimeException e) {
        throw new BpmnError("errorOne");
    }
}

Thanks

P.S. Postman returns 500 with Internal Service Error as a message when a BpmnError or RuntimeException is thrown.
