I am attempting to run a model that iterates rasters and computes zonal statistics returning a table. The raster's statistics are computer across all polygons in a specific shapefile. This model worked for a small amount of files (3), but when I am trying to use it for my entire Geodatabase it will not work, returning the error shown below. 
My model looks like this: 
I have around 300 rasters I am trying to find the statistics for, and they are listed in my geodatabase like this: 
I am using the file pathway of a new folder followed by %Name% as shown in the Model Diagram. When executing the model non-iteravely,it completes when the file name is something random, say, "new", but when using the /%Name% as the file name, it returns that the characters are invalid.
I am very confused as to why this model worked for the test run of just a few files but not for the entire geodatabase.
