Hello,
My organisation is palnning to use Talend MDM tool suite and for that I installed MDM tool set and doing a demo.
I have installed and working with Talend MDM, also enjoied working MDM_DEMo project.
Now I have created a Data Container, Data Model, Entity and View in Studio. When I am logging in to Web UI then I can see my Entity/table there. Now when I try to load data into that entity, I am getting below error,

Hi
Do you use RDBMS or XML DB as the MDM hub database? From your screenshot, I see the model name and the container name are different, if RDBMS, the model name and the container name should be the same.
