There is an error in XML document (1, 43464).

' ', hexadecimal value 0x1F, is an invalid character. Line 1, position 43464. 

I used the following SQL query to search through the parameters to find which one(s) contain the 1F hex value

SELECT Name 

FROM v_Collection 

WHERE CONVERT(varchar(max),convert(varbinary(max),convert(nvarchar(max),Name)),2) LIKE ‘%1F%’

Here is what we got:
