+==== Troubleshooting Async Configuration Issues
+
+Sine Sleuth uses a Bean Post Processor (BPP) to modify executors the `Executor` type that you provided will be modified and the return type will be the trace version of that executor. That can lead to exceptions simillar to this
+
+```
+12:12:49.606 [main] DEBUG org.springframework.context.annotation.AnnotationConfigApplicationContext - Closing org.springframework.context.annotation.AnnotationConfigApplicationContext@2401f4c3, started on Wed Jan 19 12:12:49 GMT 2022
+Exception in thread "main" org.springframework.beans.factory.BeanNotOfRequiredTypeException: Bean named 'exampleConfigurer' is expected to be of type 'com.example.demo.Gh29151Application$Example' but was actually of type 'org.springframework.cloud.sleuth.instrument.async.LazyTraceAsyncCustomizer'
+```
+
+If you see such exceptions you must
+
+* disable sleuth async
+* manually instrument the executors using their trace representations
