is one piece episode 874 filler?

Having escaped from Cacao Island, Sanji flies Luffy through the air toward the Thousand Sunny, but has to dodge cannon fire from the Big Mom Pirates' fleet. They eventually reach the Sunny, and are embraced by their crewmates.

The crew is overjoyed to learn that Luffy defeated Katakuri, and Chopper gets to work mending Luffy's injuries, with Sanji leaving his own injury for later. However, the Straw Hats are not out of the clear yet as Smoothie and Daifuku's fleet gets closer to them and harasses them with cannon fire.
