Using docker, so I have pulled the latest images of Zeebe broker and simple monitor. I have also installed the latest Modeler. Awesome job guys!. You are building a great tool here for the community.
Running into a sticker though:
With upgraded Zeebe Java client to 0.21, Simple Monitor to 0.16 and Modeler to 0.7 and updates to zeebe-docker-compose/simple-monitor/docker-compose.yml to use this latest versions as follows:
zeebe:
container_name: zeebe_broker image: camunda/zeebe:latest environment: - ZEEBE_LOG_LEVEL=debug
monitor:
container_name: zeebe_monitor
image: camunda/zeebe-simple-monitor:latest
environment:
- spring.datasource.url=jdbc:h2:tcp://db:1521/zeebe-monitor;DB_CLOSE_DELAY=-1
After I execute docker-compose up broker appears to come up correctly indicating version 0.21.
However, when I attempt to execute an existing workflow which still works with broker and Java client 0.20, I get this exception:
