Tun-time error 457

Excel Facts

When did Power Query debut in Excel?
Although it was an add-in in Excel 2010 & Excel 2013, Power Query became a part of Excel in 2016, in Data, Get & Transform Data.
Runtime error 457 occurs when trying to add a key that already exists to a collection that only accepts unique keys.
For example: If the unique-key collection has one key, and the value for that key is: "ABC" and you then try to add a second key similarly called "ABC", you'll get error 457.

You say the value of the array is EMPTY... is the code, by any chance, attempting to add another key that is EMPTY?

Did you look at the value of what you're passing in (pageurli)? Is it empty?

If not, could you supply a little more detail as to which line, specifically, the error occurred on, what's being passed to it, and what review_status is (what kind of object/class/??? is it)?

Many thanks!
