Hi Quoc,

Doesn’t look like anyone here has an answer for you.  I personally haven’t used websockets with the API gateway.  I do know however, that when I make a change on the gateway, I usually need to let it redeploy on Cloudfront before it behaves correctly for me…in that time I have gotten 400 errors that really confused me…but eventually, they settle.

Good luck.
