Whenever I run the test, the response I got on the error log is shown in the screenshot. Anyone who has an idea about this? please share it. It would be helpful.
There are no any errors in your screenshot, only information messages regarding each of 10 threads start/stop event
You need to have at least one Sampler, currently your test plan doesn't contain any samplers so threads don't have any work to do. Most probably you need HTTP Request sampler. If you're uncertain about HTTP Request sampler configuration - you can record your test scenario using HTTP(S) Test Script Recorder or JMeter Chrome Extension
HTTP Request Defaults doesn't create any load, it provides default values for all HTTP Request samplers in its scope (so you could perform configuration at one place and won't need to re-visit each and every sampler)
