getting non-object error only in log file

Your $data is an associate array and your trying to assign an object to it.

It shows another error

Code:

ERROR - 2017-09-11 10:01:57 --> Severity: Warning --> array_map() expects parameter 1 to be a valid callback, function 'objectToArray' not found or invalid function name

But why I'm getting my variable on the view page correctly and ONLY I get the error in the log file?
By the way, I've sent objects in $data in other controllers and they didn't raise any error even in the Log file!
