Get Queue Item by Reference

Hello, I am getting bad request error while using Get Queue Item activity with Reference filter. I have identified the issue, it is coming because I have special char in Reference name. For Example - Reference is “A&B” so when I give it in Get queue item in Reference then it does not fetch the queue item and gives the error of bad request.

Would anyone be able to tell the way to resolve this kind of scenario?

Try “A”+chr(ASCII CODE of &)+“B”
