I have been trying to upload files to S3 through PUT http request from jmeter. I am specifying the URL in the 'Path' and 'file path and mime type in the 'Files upload' section. I get 'Access Denied' response from S3. The same URL works fine through Postman and the upload succeeds. Tried Recording Postman steps with Jmeter and it returns CORS block only with the Jmeter record feature same as specifying AWS credentials in the JMeter PUT request.
Can you be a bit more specific on your test plan? (This question is probably better suited for the JMeter users mailing list, as it seems to be about the usage of JMeter)
Closing as no feedback.
