Pagination special character

I've spent almost 3 days on the problem but couldn't solve this by my own.

I build the pagination after this tutorial GitHub.

My main problem is that the element in the body, which i want to access, has a special character "$" in front of the name. It's named "$next".

I can't take

data = Table.FromRecords(body[$next])

cause there is an error cause of the "$".

This is the answer of the webservice.

I think it's one record cause i can transform it with Record.ToTable() to a table which looks like this

I've tried to delete all "$" characters with

CleanColumns = (table) as table =>
    let
        result = Table.RenameColumns(table, Table.ToRows(Table.AddColumn(Table.FromList(Table.ColumnNames(table)), 
        "New Column Name", each Text.Replace ( [Column1] , "$" , "" ))))
    in
        result;

but i ended up with an error which said "couldn't convert table to record" and much much more errors.

Other Code:

Page = (url as text) as nullable table =>
    let
        response = Web.Contents(url, [ Headers = BuildHeader()]),
        body = Json.Document(response),
        nextLink = GetNextLink(body),
        data = Table.FromRecords(body[next])
    in
        data meta [next = nextLink];

GetNextLink = (response) as nullable text => Record.FieldOrDefault(response, "$next");

Rest of the code (same as in the tutorial):

PagedReader = (url as text) =>
    Table.GenerateByPage((previous) => 
        let
            // if previous is null, then this is our first page of data
            nextPage = if (previous = null) then url else Value.Metadata(previous)[next]?,
            // if NextPage was set to null by the previous call, we know we have no more data
            page = if (nextPage <> null) then Page(api_base_uri & nextPage & expand_all) else null
        in
            page
    );

Table.GenerateByPage = (getNextPage as function) as table =>
    let    
        listOfPages = List.Generate(
            () => getNextPage(null),            // get the first page of data
            (lastPage) => lastPage <> null,     // stop when the function returns null
            (lastPage) => getNextPage(lastPage) // pass the previous page to the next function call
        ),
        // concatenate the pages together
        tableOfPages = Table.FromList(listOfPages, Splitter.SplitByNothing(), {"Column1"}),
        firstRow = tableOfPages{0}?
    in
        // if we didn't get back any pages of data, return an empty table
        // otherwise set the table type based on the columns of the first page
        if (firstRow = null) then
            Table.FromRows({})
        else        
            Value.ReplaceType(
                Table.ExpandTableColumn(tableOfPages, "Column1", Table.ColumnNames(firstRow[Column1])),
                Value.Type(firstRow[Column1])
            );

 I hope somebody can help me out cause this i driving me crazy :smileyfrustrated:
