How to specify error template's handlebars differently for each App in a server ?

[Felixmil]

Hi !

I'm trying to setup an error.html template. I followed the documentation and added manually some text in the template: it works.

However, I would like to use the same template for all my apps but change the value for the {{tile}} handlebar for each app that are on my server.

I tried to pass a value to a title parameter in the server config file but this prevented the server to start, so I guess this is not the write way.

How would you do set a different value for handlebars for each application while keeping one template ?

Thanks !
