performance testing - PUT in JMeter 415 Unsupported Media Type -

i'm new in performance tests, started using jmeter , creating own scripts. doing stress performance test on api, until post, get, patch working, stopped @ put method. need send file using put method, in postman working (in body using file type selected file, in header multipart/form-data).

i tried put file path in "send files request", parameter name: file, mime type: form-data, content encoding: utf-8.

in request doesn't give me file.

put http://10.111.30.12/api/tasks/2

put data:

request headers:

also tried put file in body data as: "file: c:\apache-jmeter-2.13\bin\api performance test\file.txt" getting 400 bad request.

please if got idea on how this, tell me too.

since you're testing api expectation need add http header manager send content-type header value of application/json.

the best way bottom of issue using sniffer tool wireshark compare what's being sent postman , jmeter , make sure there no differences.
