is one piece episode 269 filler?

Robin questions why Spandam was given rights to the Buster Call, when she is reminded with the Ohara incident. Robin has a brief flashback of the archaeologists.

Spandam tells Robin that the Straw Hats are on the island and should have already been captured (but this report was incomplete). Robin says her agreement was to let the Straw Hats go if she is captured.
