Calling [asyncError()] is not valid for a request with Async state [MUST_DISPATCH]

Question

env:
case 1:
client : springboot(1.5.12.RELEASE) + spring-boot-admin-starter-client 1.5.7

admin: springboot(2.1.1.RELEASE) + spring-boot-admin-starter-server 2.1.1

when i run client,and refresh admin app. the error is "Calling [asyncError()] is not valid for a request with Async state [MUST_DISPATCH]";

case2:
(2.1.1.RELEASE) Both the client and the server use the same version and have the same error.

Detailed errors are as follows：
