Search array in expression

Question

Hi,
I have a journey which triggers an event (first activity)
The parametrs in the event are - an array called "legs" and "customer Number" .
I am using a condition activity to check if a specific value within the array exists. 
Within the condition, I am passing the array and value as parameters using the "in" function.
Below is the expression:

If i check for the array at position 0, or at position 1, the expression looks correct with no error. However, if I want to search the whole array using "all()" the expression throws an error as below . How do I check if a value is present in all of the array?

Below is the schema structure:

Thanks in advance.

Hi @ishanivshah ,To check if a value is present in all elements of an array, you can use the "every" function in combination with the "in" function.The "every" function takes a function as its argument, which is used to evaluate each element in the array. The "in" function returns a boolean value indicating whether a given value is in an array.Here's an example of how you could modify your expression to check if a value is present in all elements of the "legs" array:legs.every(function(leg) { return leg.value === "specific value"; }); This expression will return true if the "specific value" is present in every element of the "legs" array, and false otherwise.

Hi @ishanivshah , You can iterate throught the array using below syntax: {{#each context.journey.profile.ArrayBetLegs.xxx as | legs |}}{{ legs.name }} = {{ VALUE }}{{/each}}
