Is there any wrong with my template /{file}.{ext}?

[tle5]

I try to set a Route in ocelot config file with information:

"UpstreamPathTemplate": "/app1/{version}/{z}/{x}/{y}.{all}",
"DownstreamPathTemplate": "/{version}/{z}/{x}/{y}.png"

With expectation it will match with: /app1/1/2/3/4.png
But it doesn't work. Is there any wrong with my template?
Thank you very much.

It seemed the UpstreamPathTemplate ignored the . character , UrlPathPlaceholderNameAndValueFinder

@WeihanLi Maybe it was true for the old version in 2019...
Now I don't see . ignoring... Is it quite implicit thing?

I believe that {all} placeholder (file extension) at the end is quite strange definition too. 😄
There will be no issue at all if define the route like

"UpstreamPathTemplate": "/app1/{version}/{z}/{x}/{file}",
"DownstreamPathTemplate": "/{version}/{z}/{x}/{file}"

Pay attention that the author replaces all upstream file extensions with explicit png one, which is wrong scenario.
I cannot get, why does the author replace all extensions with png? Strange!

Yes, it is wrong!
You wrote incorrect templates, and {all} is not presented in downstream template!
You need to define the route like this 👇

"UpstreamPathTemplate": "/app1/{version}/{z}/{x}/{file}",
"DownstreamPathTemplate": "/{version}/{z}/{x}/{file}"

Hope it helps!
