Odata and Table.Combine, error on powerbi.com

I’m trying to Combine two (or more) tables that are loaded from an odata source (with OData.Feed). 

It works fine on PowerBI Desktop, but report published on "Powerbi.com" doesn't refresh.

Error on PowerBI.com is:
“Message    Information is needed in order to combine data Table: Dziennik.”

Sources are:

Source named Dziennik00:

“let

    Źródło = OData.Feed("https://odata.test.io/source0", null, [Implementation="2.0"]),

    Dziennik_table = Źródło{[Name="Dziennik",Signature="table"]}[Data],

    Data = Table.SelectColumns(Dziennik_table,{"IDDziennik"})

in

    Data

”

Source named Dziennik01:

“let

    Źródło = OData.Feed("https://odata. test.io/source1", null, [Implementation="2.0"]),

    Dziennik_table = Źródło{[Name="Dziennik",Signature="table"]}[Data],

    Daata = Table.SelectColumns(Dziennik_table,{"IDDziennik"})

in

    Daata

“

Combined data source:

“let

    Combine = Table.Combine({Dziennik00, Dziennik01})

in

    Combine”
