Worker custom domain routes

I'm having trouble setting my route via wrangler.toml

[env.development]
route = { pattern = "https://development-api.example.com/trpc-auth*", zone_name = "example.com", custom_domain = true }

[env.development]
route = { pattern = "https://development-api.example.com/trpc-auth*", zone_name = "example.com", custom_domain = true }

I get this error

Cannot use "https://development-api.example.com/trpc-auth*" as a Custom Domain; wildcard operators (*) are not allowed

Cannot use "https://development-api.example.com/trpc-auth*" as a Custom Domain; wildcard operators (*) are not allowed

But then when I go set the route in the console. I can set it and it works as expected. But this is very tedious to do for all my workers. Is my configuration wrong?

This appears to work, maybe.

[env.development]
routes = [
  { pattern = "development-api.example.com", custom_domain = true },
  { pattern = "https://development-api.example.com/trpc/auth*", zone_name = "example.com" }
]

[env.development]
routes = [
  { pattern = "development-api.example.com", custom_domain = true },
  { pattern = "https://development-api.example.com/trpc/auth*", zone_name = "example.com" }
]

I'd love some clarification, explanation, or further guidance on this. I don't think I fully understand why routes and custom_domains are separate.
