sitelinks searchbox issue

I noticed in google console since I updated allinone I lost my urls in sitelink searchbox.

I noticed the difference before and after update on url structures.
Before was like this example:
“potentialAction”:{“@type”:”SearchAction”,”target”:”https://www.domain.com/?s={search_term_string}”,”query-input”:”required name=search_term_string”}}

After is like this

“potentialAction”:{“@type”:”SearchAction”,”target”:”https:\/\/www.domain.com\/?s={search_term_string}”,”query-input”:”required name=search_term_string”}}

Can you tell me if this is the issue “https:\/\/” “\/?s” and how do I fix it?
