UI and Docker's Web Application get stuck in Data Reading Phase

[GiorgosMandi]

Hello, please test your experiment again with the updated version of the JedAI-Webapp docker

[vromaniello]

I get the following error after specifying input sources and then pressing "Next" button in Data Reading Step in JedAI UI:

The input files could not be read successfully.

Details: java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Character
cannot be cast to java.lang.String (java.lang.Character cannot be cast to cast to java.lang.String)

In the terminal of Docker's Web Application I have the following:

Hi, then you solved? I have the same problem using JedAI-gui

Thanks
