[Unable to combine data] Section1/asd/TransformToList references other queries or steps

[Unable to combine data] Section1/Products/TransformToString references other queries or steps, so it may not directly access a data source. Please rebuild this data combination.

In Power BI Desktop updating finish successfully, But in Power BI Service with error

In Power Query exists:

Query 1. "Vendors" for Parameter 

let
    QueryString = " CALL GetVendorsList(); ",
    Data = MySQL.Database("IP", "DB", [ReturnSingleDatabase=true, Query = QueryString]),
    Vendors = Data[Vendors]
in
    Vendors

Query 2. Parameter "VendorParameter", that is using List from Query 1

"Apple" meta [IsParameterQuery=true, ExpressionIdentifier=Vendors, Type="Any", IsParameterQueryRequired=true]

 
Query 3.  "Products" string, separated with comma

let
    QueryString = " CALL GetVendorProducts('" & VendorParameter & "'); ",    
    Data = MySQL.Database("IP", "DB", [ReturnSingleDatabase=true, Query = QueryString]),

    TransformToString = Text.Combine( Table.ToList(Data, Combiner.CombineTextByDelimiter(",")), ",")
in
    TransformToString 

In Query 3 we get result like 'iphone6,iphone7,ipad2'


Query 4. "Indicators" that is using Query 3 result

let
    QueryString = " CALL GetIndicators('" & Products &"'); ",    
    Data = MySQL.Database("IP", "DB", [ReturnSingleDatabase=true, Query = QueryString]),
    ChangedType = Table.TransformColumnTypes(Data,{
        {"PortID", type text}, 
        {"ScanDate", type date}
    })
in
    ChangedType
