previous issue : https://github.com/spring-projects/spring-framework/issues/33095
There has been no answer since the previous issue comment, so I rewrite the issue.
You previously responded that the issue was caused by using Mono. However, the same problem occurs even when using the method you suggested, and it also happens when using coroutines. I have replied to the related comment, so please check it.
