It is impossible to come up with the comprehensive response without seeing your request configuration, a short checklist:1. Make sure to copy the file to "bin" folder of your JMeter installation or to provide the full path to the file2. Tick "Use multipart/form-data" box in the HTTP Request <https://jmeter.apache.org/usermanual/component_reference.html#HTTP_Request> sampler 3. Make sure to use correct "Parameter Name" under the "Files Upload" tab, it should be exactly the same as *name* parameter of the file input <https://www.w3schools.com/tags/att_input_type_file.asp> In general given you can successfully execute the request using Postman you could record the request using JMeter, just configure Postman to use JMeter as the proxy <https://support.getpostman.com/hc/en-us/articles/360008893713-How-do-I-configure-Postman-to-work-through-a-proxy-> , start JMeter's HTTP(S) Test Script Recorder, copy the file you will be uploading to JMeter's "bin" folder <https://www.blazemeter.com/blog/recording-file-uploads-jmeter/> and execute the request in Postman. JMeter will capture the request and store it under the Recording Controller <https://jmeter.apache.org/usermanual/component_reference.html#Recording_Controller>
