How can I retrieve all the attributes of a paper entity? PS: There is an "optional" field named attributes in which you can specify which attributes you want to be in the response but removing this option will return nothing. And if you put all the attributes manually it does not seem to function well. Some of them are not retrieved at all.
Try something like the following:
