In a Jmeter script, I have collected some data in a 2 variables using JSON Extractor using Match No as -1 in both JSON extractor. Now I need to check in a API whether 2nd variable consists data of 1st variable or not using JSR223 Assertion. The code I am using is:
// Get the value of dependentFeatID variable from JMeter variables
String dependentFeatID = vars.get("dependentFeatID")
// Check if dependentFeatID is not null
if (dependentFeatID != null) {
// Split the dependentFeatID into an array of IDs
String[] dependentFeatIDs = dependentFeatID.split(",")
// Check if dependentFeatIDs array is not empty
if (dependentFeatIDs.length > 0) {
// Get the first ID from dependentFeatIDs array
String searchString = dependentFeatIDs[0]
log.info("searchString: $searchString")
log.info(dependentFeatIDs[1]+"AND "+dependentFeatIDs[2])
// Get the value of featureIDs variable from JMeter variables
String featureIDs = vars.get("featureIDs")
// Check if featureIDs is not null
if (featureIDs != null) {
// Split the featureIDs into an array of IDs
String[] ids = featureIDs.split(",")
log.info(ids[0]+"AND "+ids[1]+"AND "+ids[2]+"AND "+ids[3])
boolean idFound = false
// Iterate over each ID in the array
for (String id : ids) {
// Trim any leading or trailing whitespace from the ID
id = id.trim()
// Check if the current ID matches the search string
if (id.equals(searchString)) {
// If the ID is found, set idFound to true and break out of the loop
idFound = true
break
}
}
// Set the assertion result based on whether the ID is found
AssertionResult.setFailure(!idFound)
if (!idFound) {
AssertionResult.setFailureMessage("ID not found in var_id: $searchString")
}
} else {
// Log an error if featureIDs is null
log.error("featureIDs variable is null")
AssertionResult.setFailure(true)
AssertionResult.setFailureMessage("featureIDs variable is null")
}
} else {
// Log an error if dependentFeatIDs array is empty
log.error("dependentFeatIDs array is empty")
AssertionResult.setFailure(true)
AssertionResult.setFailureMessage("dependentFeatIDs array is empty")
}
} else {
// Log an error if dependentFeatID is null
log.error("dependentFeatID variable is null")
AssertionResult.setFailure(true)
AssertionResult.setFailureMessage("dependentFeatID variable is null")
}
But I am getting Null Pointer in Method Invocation error while executing. While the JSON path I have used to extract data is tested and I am getting values as well for both variables. Please help me here. Here is detailed logs from jmeter console:

If you're using Beanshell each statement must end with a semicolon, to wit instead of:
String dependentFeatID = vars.get("dependentFeatID")
you need to use
String dependentFeatID = vars.get("dependentFeatID");
and so on
However a better idea would be switching to Groovy language, this way you won't have to add semicolons as Groovy is more tolerant. Moreover it's recommended to use Groovy for scripting since JMeter 3.1
