This is could be caused by the fact that you try to change or view an entity you don't have rights to. You could look at the on click action of the data grid and look into the different entities that are involved in this micro or nanoflow. Then check whether or not the user you were logged in as has the appropriate rights for them.

And did you find another message in the logging close to this one? Sometimes also more elaborate messages are produced that give more insight in what triggered this error.
