[Routing] LookupError: no template for url_hash=''

[rhurlbatt]

I am trying to make the upgrade to v2.1 but seem to be having troubles moving to the new template version of routing.

Here is a clone link

Basic premise is that I have an app built without templates and would like to roll over the code to a template version.
I have changed my start up form which used open_form() after running some login functions.

I have now moved this to a start up module which calls routing.launch() but it raises an error that I presume means the home form is needing a template?

LookupError: no template for url_hash='' # error raised from routing.launch()

I intend on using the templates but only for limited access views, the rest of the time I wanted to get away with just using the default template (ie MainForm).

What am I missing here? It feels like I am doing something dumb but cannot find it for the life of me!

You just need to import MainForm into startup module + any other routes and templates

If you are using a Startup Module or a Startup Form all the TemplateForms and RouteForms must be imported otherwise they will not be registered by the routing module.

I see this now... 🤦‍♂️

Atleast I was right about one thing ... I was doing something dumb 😃

Thank you Stu!!
