Processes randomly failing evaluating delegate expression


#1

Hello All,

We are on Camunda 7.6.2 EE and applied required patches.

Randomly processes are getting stuck with below exception message
Unknown property used in expression: ${updateMessageTextDelegate}. Cause: Cannot resolve identifier ‘updateMessageTextDelegate’

${updateMessageTextDelegate} is a spring component bean and declared as needed in java class. Issue is random that this class is invoked sometimes and fails sometimes with above error.

@Component(“updateMessageTextDelegate”)
public class UpdateMessageTextDelegate implements JavaDelegate {

Please share your valuable thoughts. Appreciate the help.

Thanks,
Manoj

Hi,

Do you have a cluster setup? Is it possible the bean is deployed on one not but not another?

Thanks for the response.

Bean is deployed to both the pods of K8.

We found a camunda instance with old code base processing transactions from same database and causing these exceptions. We are seeing no issues after bringing down the instance with old code. Thanks.
