I'm having an issue importing data into entities from excel or other data sources.
My option to get data from excel is greyed out.

When I try to "get data" using the button, I can navigate to the file and choose the table, but when I click the "transform data" i get an unexpected error message with the following text
section Section1;
shared Query = let
Source = Excel.Workbook(Web.Contents("https://my_sharepoint_site_library/facilities.xlsx"), null, true),
Navigation = Source{[Item = "Table1", Kind = "Table"]}[Data]
in
Navigation;
any assistance would be much appreciated.
