It seems strange that this is a flake, the error should be thrown by V8 when the object cannot be deserialized somehow.

Unfortunately we don't have a lot of information about where the exception comes from, the JS stack is lost due to asynchronicity, maybe we can tweak the wpt harness a bit to capture the stack (not sure if it's already lost by then though)

I wonder if could be related to #49713 compare_Blob function uses Response().arrayBuffer() which internally would be using streams to get the data. will try to reproduce this

That could be a cause, we can try stress-testing a revert

Does it not seem to be happening on macos? I tried locally with --repeat 1000 but no reproduction would be weird if this was os specific

Sorry for the delay, I was on a trip last week. I'm going to take a look as soon as possible.

src: avoid making JSTransferable wrapper object weak
78a1570 
JSTransferable wrapper object is a short-lived wrapper in the scope of
the serialization or the deserialization. Make the JSTransferable
wrapper object pointer as a strongly-referenced detached BaseObjectPtr
so that a JSTransferable wrapper object and its target object will never
be garbage-collected during a ser-des process, and the wrapper object
will be immediately destroyed when the process is completed.
