Dynamic segment not allowed when forwarding. Use a static path instead

[znewbiez1001]

Hi there,

I've just upgraded my company's code base to the latest Phoenix 1.7.0
We used Umbrella structure, when I recompile the whole source code, I ran into this error on top-level Router as shown below:

Dynamic segment "/:locale/my_child_app_endpoint" not allowed when forwarding. Use a static path instead

Because this is private project so I can just show you pseudo codes in Routers which caused error:

Any workarounds for this? Thanks in advance!
