or function in Custom Action

[MYSTERIOUSMAN]

Hi @SatheeskannaK @dugganab @DavidKangni 
when i am passing a string with some personalization in this from the event activity "Have a few seconds or call" +#event attribute it is taking or as a function not as a string can you let me know how to resolve this.

It's just in the display but if you send out the payload (assuming it is a custom action), it shows up correctly.

when i testing it having or in it custom action is getting failed getting http error and when and when i am removing or it is working fine

i tried doing a concat as well 
(concat(["or"," ","call"," "])) -- not working 
but if i do (concat("or","call")) it is working but the words are getting together  orcall
