By default ready api sends this as application/octet-stream but the end point expects application/json Rest request attachments multipart form data for json file with parameterized json data So I have been trying to do a scenario where i have two attachments for a rest request, one json file which i need to parameterize couple of fields from previous request. The problem with this is once you have cached the attachment you cannot modify it based on the previous test steps, So i have followed the following youtube link https://www.youtube.com/watch?v=iL-zehJmtWw Used query parameter to use a locally store file of json to request but we are getting the error from response that application/octet-stream content type is not accepted ------=_Part_01_136051460.1696260652738 Content-Disposition: form-data; name="testFile" testFile:/Path/to/file/testFile.json I have used parameter like this testFile:${projectDir}/testFile.json What should I do in this case
