I am trying to use Camunda 8 self -managed. I have a spring boot application set up with Zeebe client.
I get the error displayed below while starting the application.

Error starting ApplicationContext. To display the conditions report re-run your application with ‘debug’ enabled.

Hi @Supriya ,

I think that this might be because of the versions’ incompatibility. Kindly check this, for the inter compatible versions of spring boot, zeebe and camunda versions, and try.

Also, spring-zeebe-starter dependency is now marked as legacy. Instead you should use, spring-boot-starter-camunda , and you can remove the dependency of zeebe-client-java and spring-boot-startersince they come as compile dependencies in spring-boot-starter-camunda (i.e., You can cleanup all the 3 dependencies with only one dependency spring-boot-starter-camunda). Also this helps in manual version incompatibilities.

Hope this helps you move forward.
