scheduled refresh csv + table combine Error ?

Hello,

I have a problem with the scheduled refresh for my reporting (It works fine on pbi desktop).

For 4 tables of my data model, I need to combine 2 csv (the csv are in a server and I call this files directly by url).

Each morning, I have the following message : "Information is needed in order to combine data Table: xxxxxx".

----------------

Example call for one combine table :

Table 1 -> Csv.Document(Web.Contents("http://www.xxxxx.fr/my_file_1.csv"),[Delimiter=";", Columns=8, Encoding=65001, QuoteStyle=QuoteStyle.None])

Table 2 -> Csv.Document(Web.Contents("http://www.xxxxx.fr/my_file_2.csv"),[Delimiter=";", Columns=8, Encoding=65001, QuoteStyle=QuoteStyle.None])

Final table -> Table.Combine({#"Table1",#"Table2"})

------------------

How I can solve this problem please ?

Thank you,
