Recently, I started to learn JMeter by myself, but I found an error when running the interface (the interface has passed the postman, and finally found the reason after self-examination)

First, the error prompt: we mainly look at error. We can see error o.a.j.jmeter: uncaught exception in thread thread [awt-eventqueue-0,6, main], and then look down to see relevant fields such as darkfilexxx. It can be solved by changing the dark skin directly, as shown in the figure below:
