Hi @PeCour , I was able to identify the problem. Can you please try the following?
In the ‘Upload file to storage bucket’ rule, in the ‘When completed section - Set Value’ rule, instead of setting the process input argument ‘in_dateiname’ with the ‘uploaded file name’, please create an app variable and set the ‘uploaded file name’ to it.
You can then set this app variable to the in_dateiname in the input override of the process. That should work.
In case you still face trouble, kindly let me know.
The yellow circle is an app variable
You can use this app variable to set it to the input argument of the process through input override as shown below
