Steps to reproduce

If necessary, I can provide the minimum sample project.

Observed Behavior

Circular reference error occurred.

Here is my sample project

How-to-run:

Modify the following configuration in application.yml file.

cloud:
  consul-host: 127.0.0.1
  consul-port: 8500
  pgsql-host: 127.0.0.1
  pgsql-port: 5432

You can run following command to start consul and postgresql service.

docker run -d --name=consul-dev -p 8500:8500 hashicorp/consul

mkdir -p /dev/pgsql

docker run -d --name postgres \
    -e POSTGRES_PASSWORD=camunda \
    -e PGDATA=/var/lib/postgresql/data/pgdata \
    -v /dev/pgsql:/var/lib/postgresql/data \
    -p 5432:5432 postgis/postgis

There is also a triggering condition for this issue, where time events are used as starting events in bpmn.

Hi @royalzzz,

I've found this old issue: https://github.com/camunda/camunda-bpm-spring-boot-starter/issues/148 I tried it and after adding the @EnableProcessApplication annotation the problem disappeared.

I hope it helps. If the problem still persists, feel free to reopen the issue.
