Jmeter Response Data dissapears in the "View Results Tree" Panel After Re-Opening The .jmx File

I am using Apache JMeter 5.4.1 to record a manual test script (to be automated later) on a web application.

I need the response data logs which are recorded in the View Results Tree for debugging purposes.

I don't want to run the script before debugging, because I need to parameterize the dynamic data which changes every run thus, I need to capture them using the response data.

The problem is, I need to save the file and continue later sometimes, and when I open the file and load the .jtl file into the View Results Tree, the response data doesn't show up. Like it never existed. I can still see the results but when I click on them I see "No Data".

What causes this strange phenomenon, and how can I work around this? Thank you!

By default JMeter doesn't save response data, if you're using View Results Tree listener in GUI mode you need to additionally instruct it to save the results as XML and explicitly tell it to store response data, example setup:

If you're running the test in command-line non-GUI mode - amend Results File Configuration in user.properties file to look like:

jmeter.save.saveservice.output_format=xml
jmeter.save.saveservice.response_data=true
jmeter.save.saveservice.samplerData=true
jmeter.save.saveservice.requestHeaders=true
jmeter.save.saveservice.responseHeaders=true
jmeter.save.saveservice.url=true
