Get Queue Items Activity Assistance

Hi! I’m working with REFramework and I’m adding 2 items to the queue, the email sender and the email subject. If the email subject equals to a specific string, the whole bot runs. Otherwise, I wand those items to change to business exception.
For this procedure, I’m using getQueueItems and SetTransactionStatus.
I need help with the getQueueItems activity, I do not know how to filter by reference
I want the output to have the items where the reference for the email subject isn’t equal to “Stringx”


Hey @Daniela_Valdez_Luis

Remove the Not keyword from the reference field as you are passing Boolean which is wrong. You need to just pass string which is the reference.
