How to reference list of lists in Table.RenameColumns function?

Table.RenameColumns takes two values -- the table you want to modify, and a list (or list of lists) containing the old and new column names. 

Example given in Power Query documentation:

Replace the column name "CustomerNum" with "CustomerID" and "PhoneNum" with "Phone" in the table.

Table.RenameColumns( Table.FromRecords({[CustomerNum = 1, Name = "Bob", PhoneNum = "123-4567"]}), { {"CustomerNum", "CustomerID"}, {"PhoneNum", "Phone"} } )

I have a list of lists in another query that I tried using in this function. However, I'm getting an error/the function is not accepting my list of lists. 

I created two codes that you can use to replicate the data and all my steps, which you can paste directly into the advanced editor to create a new query.

Code for the list of lists:

let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WilHyz0nxS8xNNYxRUtIBcv1Sy2HcWB0keSNUeSN0eWNUeRA3NhYA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [OldNames = _t, NewNames = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"OldNames", type text}, {"NewNames", type text}}),
#"merge old name and new name columns" = Table.CombineColumns(#"Changed Type",{"OldNames", "NewNames"},Combiner.CombineTextByDelimiter(",", QuoteStyle.None),"Old and New Names"),
#"create list of lists" = Table.ToRows(#"merge old name and new name columns")
in
#"create list of lists"

And here is a code which contains the table I am trying to apply the function to, and the failed result:

let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WSkksSTRU0gHTRlDaWCk2FgA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [OldName1 = _t, OldName2 = _t, OldName3 = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"OldName1", type text}, {"OldName2", type text}, {"OldName3", type text}}),
#"run table rename columns function" = Table.RenameColumns(#"Changed Type", #"list of lists")
in
#"run table rename columns function"

When I run the Table.RenameColumns function, I get the error:

Expression.Error: We expected a RenameOperations value.
Details:
[List]

But #"list of lists" is a list, and should be formatted exactly like the list of lists used in the documentation example I provided, no?

I appreciate any help that can be provided...
