DataSource.Error: OData: Unsupported query option encountered: $expand

I am using PowerQuery on a OData source pointing at MS Project Online. 

One of the columns in my query is type "Record".

When I expand the column, I can choose the columns I want, but the result is the error as titled...

DataSource.Error: OData: Unsupported query option encountered: $expand

What am I doing wrong? How do I solve it?

if you right click on the column you would like to expand, and select unpivot then you will be able to expand it 

Thanks @amitchandak,

I have seen those links already, but they are not helpful. 

 

Maybe I should rephrase my question: How do I convert a column of data type records to a column of data type table. I'm not expecting a solution, since the problem is not actually inPowerQuery, but rather in the underlying data provider. 

The PowerQuery function 

 

= Table.ExpandRecordColumn(Filtered, "Time", {"TimeMonthOfTheYear"}, {"Time.TimeMonthOfTheYear"})

 

would theoretically do the trick, but since the data provider bombs out, it won't work. So now I'm wondering if I must have some sort of custom function approach to read each record and extract this one field that I want from the record.
