While using the OLE DB Source component in SSIS, on updating its SQL Command we started getting the below error for “Phone” column in our Table.
The fix is to open the Advanced Editor for the OLE DB Source component
Change the Data Type (non-unicode string) for the Phone column inside Output Columns in Input and Output Properties Tab.
Changing the Data Type from Unicode string [DT_WSTR] to string [DT_STR] fixed the issue.
Hope it helps..

I have a similar issue and I applied the recommended solution but still that didn’t work
