Issue with contains filter


Hello, @Erick!


Could please provide us with a little bit more information? Perhaps some screenshots or an error message? 


Thanks you in advance! 




Hello Rodrigo,

It's very weird and I succeeded finding a workaround. Let me explain:

I have 2 arrays of objects and I want to find what items in the 2nd array exist in the 1st array.

I know it can be done using 'Apply to each' but it can take time depending on the number of items in the arrays.

Consequently I tried using the 'Filter array' action with 'contains'.

In the From field I put the 1st array (Output) and under: 2nd array (varBestUsers) - Contains - item().


Unfortunately it doesn't work: nothing is found.

However I found a workaround to make it work:

I replaced item() by:

json(concat('{ "UserID":', item()?['UserID'], ',"InteretID": ', item()?['InteretID'], '}'))


Can you explain why item() doesn't work and it does with the JSON clause doing the same thing?

I believe that your issue could have been solved by using a union() expression.

@ScottShearer Can you tell me how to use union in my case?


Sorry, I should have said intersection() and not union()

My understanding is that you want to find the common elements between two arrays:

Hi @ScottShearer, Thanks for your response. In fact intersection or contains functions only works with strings and not numbers (after Select or Get items). Once I converted all numbers to strings it eventually worked.
