Karate-robot error : com.intuit.karate.StringUtils.split(Ljava/lang/String;CZ)Ljava/util/List;

Question

I am trying to upload file to a vaadin-upload component using karate-robot and getting this error: com.intuit.karate.StringUtils.split(Ljava/lang/String;CZ)Ljava/util/List;

Here is the message in log:

I am trying to run this on vscode in Mac. Here's the feature file data:

Feature:   
Background:
    * configure driver = { type: 'chrome', headless: false  } 
    * configure afterFeature = function(){ karate.write({ id: jamaId, errorMessage: karate.info.errorMessage }, 'jama-id-' + jamaId + '.json'); }
    * call read('runsetup/ui_login.feature')
  
Scenario: Verify UI: Default Regulatory Mode Filter to IVD
    * click("{}Applications").delay(1000)
    # * driver.inputFile('#installAppButton', targetDir+"/resources/utilities/ivdDummy1.app")
    * robot { window: '^Chrome', highlight: true }
    # since we have the driver active, the "robot" namespace is needed
    * waitFor('#installAppButton').click().delay(1000)
    * robot.input(targetDir+"/resources/utilities" + Key.ENTER)
    * robot.waitFor('ivdDummy1.app').click()
    * robot.input(Key.ENTER).delay(1000)
    * submit().click('#file-submit')
    * screenshot()
