Unable to use POST v1/session/:sessionId/load

[akaikrai]

After sending a zip archive of a build to my roku device I get a "socket hang up" error. After some digging i discovered that it most likely has to do with CORS and strict-origin-when-cross-origin header.
I assume that the session drops after attempting to load a zip file from my local machine to the device because of security measures taken to prevent CSRF attacks.
Is there a workaround?

We are also trying to achieve the same thing. We are tying to call the side load API from Postman and we are getting the following error.

We have tried with the zip file alone and also the whole path of zip file in the request body. Both are giving the same response.
Where is the channel.zip file expected to be while testing using postman .We are not sure where we are going solution. Can someone help.
