Reporting no Information on error

Until recently, If I had an error in a jasper.jxrml I did get the exception error in the UI and was able to correct it.
With the actual Version of JMix 2.5 I get a generic error

Is it possible to set a flag, so I get the more detailled information about the error like in the past ?

I cannot tell the normal user to use a IntelliJ to debug the program …

Can you provide a test project where the problem is reproduced?
