Applying AUTOML MODELS results in DATA IMPORT PROBLEM: I GET ERROR Expression.Error

[Paolone]

after I unpoload my training data, chose a model train it and become redy to apply to a new data set I experience the following problem when I save the data set on which i want to do the prediction 

if I upload the testing dataset with the training data set i do not get this error.

I am not a software engineer so I would appreciate a creal and contextualized answer, with all the concepts explained without assuming concepts known.

Whether it uses two different data sources which could cause FireWall issue, if so, please try to make sure that the privacy level for both data sources is compatible (Public/Public or Organizational/Organizational).

See: Expression.Error: Cannot convert the value "[Function]" to type Function 

If only a single data source, you can consider clicking 'Show details' on the error message page to show detailed error about this issue.
