Error connecting Spring boot app with Camunda 8.6.6 Run

Camunda 8 Topics Discussion & Questions

I have setup Camunda 8.6.6 in Windows10, and I can access Operate and Tasklist. However, when I try to connect a simple Spring Boot project using spring-boot-starter-camunda-sdk, I’m getting below error in ZeebeDeploymentAnnotationProcessor

Caused by: io.grpc.StatusRuntimeException : UNAVAILABLE: Expected to execute command on partition 1, but either it does not exist or the gateway is not yet aware of it.

I had a look into the camunda.log file, and I can see below exception though I can access Operate and Tasklist.

io.camunda.zeebe.util.actor- Uncaught exceptionin ‘Startup’ in phase ‘STARTED’. Continuing ith next job.
java.lang.UnsatisfiedLinkError: ‘int org.rocksdb.RocksDB.version()’

I’m not sure if the latter rocksdb error has anything to do with the former grpc connection error while deploying the bpmn file I have mentioned with @Deployment annotation.

FYI, I’m simply using camunda.client.mode=self-managed property, and falling back with the other default properties.

Hi @Sankar - that’s not expected. I would recommend trying a clean start: shutdown the running instances, remove the downloaded artifacts, and start C8 Run again. Zeebe uses RocksDB for temporary local storage and if Zeebe can’t connect to RocksDB, it can’t start.
