Object reference not set to an instance of an object.

Hi guys,

Finally, after review each code running and each relation into the Power BI Model, I found the error. One of my complex scripts were making a relationship with my main table and the moment to refresh my report "PUM" error. I took the decision, for now, to eliminate table and relationship and my report back up to "life" again, I going to check-up well the code and consequences into my model.

I want to express my gratitude to the people who tried to help me with this issue. I promise to do the same if someone else needs it.

Regards;

Jairo Suarez
