Question

Lassie sometimes returns CARs with missing blocks even after sending a 200 and without any unclean close

As part of Onion testing, we see that Lassie sometimes returns CARs for successful reads(no unclean closes) that have missing blocks.
This is easy to reproduce.
Here are some paths you can try downloading from Lassie -> you will get the CAR successfully but it will have missing blocks for some links.

@aarshkshah1992 what leads you to believe they are missing links? When I download over lassie, I certainly can extract the requested image

Is this reported by Nginx? Caboose? L1-Node?

@hannahhoward

This is reported by Onion while talking directly to the Lassie container
Please can you share the code you use to extract this image ?

Closing the issue as Hannah is able to extract the images.
