400 bad request

Hi,

I have following query in my pbix but when i try to close&apply changes I'm receiving bad 400 request:

let
Source = (VersionsRelevantSharePointListName as text, VersionsRelevantSharePointLocation as text, VersionsRelevantItemID as number) => let
Source = Xml.Tables(Web.Contents(
"https://xxx.sharepoint.com/sites/",
[RelativePath = VersionsRelevantSharePointLocation & "/_api/web/Lists/getbytitle('" & VersionsRelevantSharePointListName & "')/items(" & Text.From(VersionsRelevantItemID) & ")/versions"]
)),
entry = Source{0}[entry],
#"Removed Other Columns2" = Table.SelectColumns(entry,{"content"}),
#"Expanded content" = Table.ExpandTableColumn(#"Removed Other Columns2", "content", {"http://schemas.microsoft.com/ado/2007/08/dataservices/metadata"}, {"content"}),
#"Expanded content1" = Table.ExpandTableColumn(#"Expanded content", "content", {"properties"}, {"properties"}),
#"Expanded properties" = Table.ExpandTableColumn(#"Expanded content1", "properties", {"http://schemas.microsoft.com/ado/2007/08/dataservices"}, {"properties"})
in
#"Expanded properties"
in
Source

I guess I need to add something to web contents but I'm not sure what would that be.

Thank you in advance for help!
