Arcade: Escape Character for URL containing {}

mgold_timmons — Tue, 04 Nov 2025 21:58:31 GMT

I am trying to add a URL to a pop-up using the Arcade element, but the URL contains values inside { } and Arcade is removing that entire portion from the returned result. I can't find any helpful escape characters to negate this.

This is an example of the URL:

https://clientURL/?search={[Property Card]:[Sec_Block_Lot] = "77-3-34"}&openlfoneresult=true

This whole section: {[Property Card]:[Sec_Block_Lot] = "77-3-34"} is removed and instead, I get:

https://clientURL/?search=&openlfoneresult=true

When I try the escape character {{ }}, it returns https://clientURL/?search=}&openlfoneresult=true

I've also tried urlEncode(), subbing in %7B and %7D as encoded values for {}, and \ as an escape character, but none of those have worked. I also tried using a normal text element and adding in the URL as a link with the same truncated result.

Is there something obvious I'm missing? I appreciate any help!

Try using the escape character "}" for "{" and "}" for "}". This syntax seems to work

var output = `https://clientURL/?search={[Property Card]:[Sec_Block_Lot] = "77-3-34"}&openlfoneresult=true` return { type : 'text', text : output }
