https://github.com/making/demo-configdata is a reproducible sample.
Reading properties itself works.
I tried with both 2.4.0-M4 and latest 2.4.0-SNAPSHOT.
Comment From: dogganidhal
For me it's the /actuator/configprops endpoint that throws this exception when using configtree:...
Spring Boot : 2.5.0
Comment From: snicoll
@dogganidhal if you believe you've found a bug in Spring Boot, please try against the latest 2.5.x version and open a separate issue with a small sample that lets us reproduces the problem.
Comment From: dogganidhal
Hello @snicoll,
Well I've tried the latest stable version of spring boot as of today (2.5.2), the issue is still there
Here is a demo project : https://github.com/dogganidhal/configtree-actuator-demo
You will need to edit the property spring.config.import to match the clone path in your local machine
