Failed to execute initialization process

Hello ,

I got an error running the process on the web app ， but I can execute the process normally in studio.

I've found a similar problem here. https://community.rapidminer.com/discussion/55914/webapp-failed-to-execute-initialization-process-which-previously-worked ，But my version is 9.3.2. Is this another bug, or am I not doing the right thing?

The error message is shown below.


in the server.log . it looks like a NPE .

The attachment is the part I took from server.log.

    Hi @lzu ,
    Unfortunately the problem with the WebApps is 2-fold where only 1 part has been fixed in 9.3.2.
    You probably use the Operator "Execute Process" in your initialization process. This problem occurred just lately but we have identified and fixed this bug.
    It will be released with the upcoming RapidMiner Version 9.4.1.
    Happy Mining,
    Edin

    The latest RapidMiner version with fully working WebApps is Version 9.3.0.
    Although this is generally not recommended, in this special case you can replace the rapidminer-server-9.3.2.ear file with the rapidminer-server-9.3.0.ear file. It is located in the the standalone/deployments/ folder of your RapidMiner Server installation folder.
    Please make sure that you have shut down the Server beforehand!

    Thanks Edin ，

    Where can I download to version 9.3.0?
    I click the Full Server Package to download only to version 9.3.2， When I try to select a different version ,Only see before 9.3 to other versions .





    Best,

    Tanks @sgenzer ,
    What does DM mean?
    I'm a Chinese, so I don't particularly understand what this shorthand stands for .
