Could you please provide the code you are using to get the data and how your query is configured?
From the log I can see you are asking for interpolated values. Indeed, InterpolatedValuesByCount does not accept a timespan of zero and this is by design. Is there another way you can get this data? Is there a specific reason to ask for interpolated values with no interval at all?

Adding to Rafael Borges questions, why are we trying to retrieve interpolated data from a table that does not provide the time context? Why not just use a GetValue method ?
It's working with attributes with a formula DR because one of the input to the formula has a data reference with a time context (PI Point or Table Lookup from a table with time context).
The versions mentioned are that of .Net Framework your application was compiled against. Would it be possible to share the version of AF SDK which will be the same as that of PI System Explorer on that node. You can get the information either from Help > About PI System Explorer or from the control panel (AFClient).
Hope this helps,
