Debug SQL Server Errors in SSIS

Please I have created an SSIS Package and make four tasks:

LoadCustomerScript: to populate my customer dimension Located in LightAdventureWorksDW2017 (created by me)

--Product data flow: contains two tasks extract data from the product dimension of AdventureWorksDW2017 sample and load data to load the data to the product dimension of LightAdventureWorksDW2017

--Date data flow: contains two tasks extract data from the date dimension ofAdventureWorksDW2017 sample and load data to load the data to the date dimension of LightAdventureWorksDW2017

--InternetSales data flow

when I run the sequence container the three tasks run successfully (customer, product and date data flows) but the internet sales don't and I don't know why

and am getting those errors :
