Spring Boot Admin illegal character while health check - spring-boot

Question

I have deployed few Spring boot applications using spring cloud Netflix OSS and configured Spring boot Admin to monitor those application connecting to Eureka server. But for two of the applications, I am getting below error. Could you please let me know what could be the cause of this error and how to mitigate this.
This endpoint health URL is provided by Spring boot actuator and output of the heath URL is {"description":"Spring Cloud Eureka Discovery Client","status":"UP"}
Error in the log

Answer 1

There was an extra space at the end of the URL
eureka.instance.healthCheckUrlPath=${management.context-path}/health
It should be
eureka.instance.healthCheckUrlPath=${management.context-path}/health
