The value violated the integrity constraints for the column while executing SSIS package

I have created SSIS package which basically extract the dirty data from the table and using DQS Cleansing Transformation clean the data and load into tables according to Lookup Transformation criteria. I am getting below error at the end of the process.

Error: 0xC0202009 at Data Flow Task, CustomersDirtyNoMatch [109]: SSIS Error 
Code DTS_E_OLEDBERROR.  An OLE DB error has occurred. Error code:0x80004005.

Here's a table definition

CREATE TABLE dbo.CustomersDirty (
    CustomerKey INT NOT NULL PRIMARY KEY,
    FullName NVARCHAR(200) NULL,
    StreetAddress NVARCHAR(200) NULL,
    Updated INT NULL,
    CleanCustomerKey INT NULL);

CREATE TABLE dbo.CustomersClean (
    CustomerKey INT NOT NULL PRIMARY KEY,
    FullName NVARCHAR(200) NULL,
    StreetAddress NVARCHAR(200) NULL );

CREATE TABLE dbo.CustomersDirtyMatch (
  CustomerKey INT ,
  FullName NVARCHAR(200) NULL,
  StreetAddress_Source NVARCHAR(200) NULL,
  StreetAddress NVARCHAR(200) NULL,
  StreetAddress_Status NVARCHAR(100) NULL,
  StreetAddress_Confidence NVARCHAR(100) NULL,
  StreetAddress_Reason NVARCHAR(4000) NULL,
  Updated INT NULL,
  CleanCustomerKey INT NULL,
  Record_Status NVARCHAR(100) NULL );

CREATE TABLE dbo.CustomersDirtyNoMatch ( 
    CustomerKey INT , 
    FullName NVARCHAR(200) NULL, 
    StreetAddress_Source NVARCHAR(200) NULL, 
    StreetAddress NVARCHAR(200) NULL, 
    StreetAddress_Status NVARCHAR(100) NULL, 
    StreetAddress_Confidence NVARCHAR(100) NULL, 
    StreetAddress_Reason NVARCHAR(4000) NULL, 
    Updated INT NULL, 
    CleanCustomerKey INT NULL, 
    Record_Status NVARCHAR(100) NULL );

As recommended I did some change in configuration. I have added Flat File Destination adapter at the end of CustomerDirtyNoMatch destination adapter. Still data is not inserted in table though error data inserted in flat file.

Please refer this flat file
