Description Felix Schumacher 2020-08-01 14:36:29 UTC 
If you try to import a curl script with a blank argument for a switch that expects an argument, the importer will throw an exception instead of using an empty string as data.

Take for example the curl script:
  
  curl --data '' https://example.invalid

JMeter will currently throw an exception on importing:

If we switch the parameters around and use the data switch with a blank argument at the end of the line like:

  curl https://example.invalid --data ''

we get the following exception:

Both exceptions have the same origin. The used parser will skip the blank argument and our logic is therefore missing the argument.
