File appears to get truncated when Posting/Upload using ReadyAPI

Hello,

I have an inconvenince that I am trying to resolve.

I am tryin to configure ReadyAPI 3.1.0 to use a specific Rest service with a POST method that is used to Upload files. From the documentation, I assume I configured the API correctly in Ready API. But when I run the commend to upload, the file size does not match and appears to get truncated. This makes the file unusable.

I tried to use the example in the Oracle site to use Postman and that works fine. I can upload the file and it looks good. Oracle said it's Ready API problem so here I am asking you all...

Ready API 3.1.0 configuration for this:

Method: POST

Request Media Type: application/octet-stream

Request Attachments:

There is an exampl here using Postman and I use that no issue.
