DirectConsumerNotAvailableException: No consumers available on
endpoint
After upgrading from 2.18 to 2.19.5, I'm often seeing this exception at startup.
It looks like the auto-started route is not immediately ready?
Using a producer template, it can happen that "DirectConsumerNotAvailableException" is thrown.
At next try (e.g. a second later) it works.
How can this be avoided?

Thanks, the block option for the direct: component helped.
However, in general, there's a more apparent timing issue after the version upgrade.
If the CamelContext is not ready, then one cannot start routes.
I had to resort to registering a "StartupListener" to be notified, before trying to start routes.

You may be interested in routes startupOrder
<https://github.com/apache/camel/blob/master/camel-core/src/test/java/org/apache/camel/processor/RouteStartupOrderWithDefaultTest.java>
or the block option
<https://github.com/apache/camel/blob/camel-2.19.x/camel-core/src/main/docs/direct-component.adoc>
which you may need to set to true on your own in 2.19.5.
