Expected single candidate for component [EventBus]

When I do not use Server and use Mongo db I get this error.

rg.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘accountAggregateRepository’: Failed to instantiate [org.axonframework.modelling.command.Repository]: Factory method ‘repository’ threw exception with message: Expected single candidate for component [EventBus].

Could you share a bit more on the application? Typically there should be only one auto configured. So maybe you added configuration to add an additional one?

In short, what is different in your app from a typical Spring app which uses MongoDB but not Axon Server?
