Need help with error

Can someone please offer me a hand ? 

I'm getting the following error message:

KeyNotFoundException : 'ES VHLE2YXR59WP' wasn't found in the Slice object, likely because there was no-data at this moment in time and it wasn't possible to fillforward historical data. Please check the data exists before accessing it with data.ContainsKey("ES VHLE2YXR59WP")

 

That being said If you look at my code I do check to see if the symbol was in the slice. I'm obviosuly doing something wrong regardless, any help would be much appreciated, Thanks !

It might be a good one to add to the documentation? =)
