Association does not lead to entity

I have been getting this error and I don't know how to fix it. I think it might be something with the database but im not sure. How do I fix this? I am trying to create a chart with DataEntry.FirstName on the x-axis and Profile.Score on the y-axis.

On your page 'Page’ you are using a custom widget to create the chart. Probably the custom widget requires an entity having attributes 'X-axis data attribute' and 'Series entity'. And the entity passed along does not have those attributes.
