Issues with route

[MollocH]

Hey folks,

I have a very very strange issue which I cannot seem to resolve.
We have a working project with about 15-20 routes already.

One of them is "POST /v1/asset" which is working fine.
My task is to change the route to accept an asset type as url parameter.

So far so good. Here is the code:

e := echo.New()
v1 := e.Group("/v1")
assetGroup := v1.Group("/asset")
assetGroup.POST("", h.createAssets) //with h being the handler

Now when I try to change the route to anything (with param or with a static value)
assetGroup.POST("/:type", h.createAssets)
assetGroup.POST("/foobar", h.createAssets)

I always get a 404. As soon as I rollback the URL, everything works fine again.

I am kind of desperate right now as I was debugging for several hours and can't seem to find the issue.
I was on echo version 4.10.3 and upgraded to 4.11.1. Did not help.

Does anyone have a hint where my problem is?

Thanks in advance for your help

Wow ... wrote the post and couple of minutes later I found that the problem was related to that specific route being marked as unprotected route. So the Auth middleware was interfering somehow -.-
