This is an old topic but I will post this reply to be able to close it.
The problem description indicates that the issue relates to the Docker version of the tool where error messages are very limited. I would guess that there is an issue with the excel file, eg. column names, the two tabs or something like that.
However, an important thing to point out is that we strongly recommend running the tool in Colab or a local Jupyter Notebook, since this will install a later version of the tool, and also provide more feedback if errors occur.
