Getting values within range from PI Web API for an AF attribute based on CDR

Hi community members!

I have an AF attribute that gets data from SQL and Oracle databases using custom data reference. I face some issues on getting its values through PI Web API.

I can get its last value from PI Web API with no errors, but I can't access range of recorded values as error appears "The data method 'RecordedValues' is not supported on attribute <ATtribute name>".

For getting values within range I'm using "Recorded data" reference in attribute links in PI Web API, is that correct? What am I missing?

 

I thought that the problem in my CDR supported methods, but changing it does not affect the result. Just in case, here are my supported methods and contexts in CDR:
