We don't know how to fix the issue because we don't know how the request should look like, moreover you don't show us "Parameters" tab of the HTTP Request sampler and HTTP Header Manager configuration.

So if you have another way of successfully calling this API like curl or Postman or other tool - you should be able to record the request using JMeter's HTTP(S) Test Script Recorder , see How to Convert Your Postman API Tests to JMeter for Scaling article for example setup.

If not, you need to check your API endpoint documentation, application logs or ask around for the proper request format, once you know it you should be able to amend the request yourself or provide us more details so we could assist.
