Hello , 
i am trying to load data from a list of 350 underlyings stored in an array.
I use the function  marketPrice.GetData(instruments, fields) 
 From the LSEG website   Tutorials | Devportal , i understand that the inputs of this function are 2 arrays (fields, instruments)
I got the following error 
    
        
            
    
What is the correct inputs of the function marketPrice.GetData ? 
Is the error coming from the number of underlying (350) requested ? 
Thanks
