Error generating the report: java.langnullpointerexception when JMeter runs on the command line

This error is caused by CSV. Error reading CSV file path,   The CSV set file is not found, and there is no result after running. This error will occur only when an error is reported in the generated report, so you only need to configure the correct file path to run successfully. During distributed pressure measurement, the file path on the slave machine is used and placed in the bin directory. The file paths of multiple slave machines are consistent. Problem solving.
