Extracting JSON and using it in if condition

Question

I need to add a condition in my thread where my next HTTP Request will execute only if the previous response has message message that says 'You can proceed with the booking.'

first response

I tried adding regular expression extractor to get MessageInfo using the below expression.

"MessageInfo": "(.*?)"

I also tried with JSON extractor using below json path expression:

$..MessageInfo

Below is the Expression that i added in if condition:

if condition

However, my execution stops after the first response and does not move into the if condition. Any help would be appreciated.

You need to use a Function or Variable which resolves to true in the If Controller in order to be able to run its children. You're giving a string which isn't equal to true therefore If Controller's children are never run

Therefore you need to use your expression in i.e. __jexl3() function

${__jexl3("${MessageInfo}"=="You can proceed with the booking.",)}
