Same code works fine in one environment but fails in another with error: wildcard segment conflicts with existing children

Description

The below is the code which runs perfectly in our QA environment. However the same code when we depoyin production environment throws error

                 r := gin.Default()
...
...
		r.GET("/events/partial", func1)
		r.POST("/events/:eventid/g2w/roles/:role", func2)
		r.GET("/events/:eventid/g2w/roles/:role/status/list", func3)
line 176::		r.GET("/events/:eventid/g2w/status/list", func4)
		  r.GET("/events/:eventid/g2w/status", func5)

Error:

wildcard segment ':eventid' conflicts with existing children in path '/events/:eventid/g2w/status/list' stack:goroutine 143 [running]:
runtime/debug.Stack(0xc000830710, 0x11ce2e0, 0xc000568fd0)
...
main.HandlerInternal(0x16bb560, 0xc00067a690, 0xc0001994d0, 0x9, 0xc0001994e0, 0xe, 0xc0001994b8, 0x4, 0xc00067a6c0, 0xc00067a6f0, ...)

To fix the above error we changed the end points to the below

                 r.GET("/events1/partial", func1)
		r.POST("/events2/:eventid/g2w/roles/:role", func2)
		r.GET("/events3/:eventid/g2w/roles/:role/status/list", func3)
		r.GET("/events4/:eventid/g2w/status/list", func4)
		r.GET("/events5/:eventid/g2w/status", func5)

We checked go.mod and go.sum files on both production and dev environments. They is no difference even by a character.

The only difference between the dev and production environment is the OS minor version difference.

ubuntu/images/hvm-ssd/ubuntu-bionic-18.04-amd64-server-20210415 → QA
ubuntu/images/hvm-ssd/ubuntu-bionic-18.04-amd64-server-20200810 → prod

Is this some kind of known issue. Anything I have to check on why the same code works in dev environment but fails in prod environment?
