**Your software**  
My Mautic version is: 5.2.4  
My PHP version is: 8.2  
My Database type and version is: MySQL 5.7

**Your problem**  
My problem is:  
When trying to either generate a user specific preview URL or send an example email, the contact search never returns a contact. I’m not sure if I’m not using them right, which fields can be used for these or if it’s because we have around 6M contacts?

Even with sending an example to a manually entered email, that dialog doesn’t seem to respond - Send and Cancel don’t close the dialog or send an email.

These errors are showing in the log:  
Chrome console shows this when opening the dialog:  
app.js?v611ae260:96 Uncaught TypeError: Mautic[callback] is not a function  
at HTMLInputElement. (app.js?v611ae260:96:252)

Then if cancel is clicked, shows slightly different error:
