What happened?

Hi,
I've these routes:

In postman if i execute:

GET --> /api/devices --> Respond OK
POST --> /api/devices --> Respond OK
DELETE --> /api/devices --> Respond ERROR (it's normal not exists route)

but if i execute with and slash "/" at the end, all routes respond as if they were GET.

GET --> /api/devices/ --> Respond OK
POST --> /api/devices/ --> Respond OK
DELETE --> /api/devices/ --> Respond OK

and I can't find where the problem is

Steps to Reproduce

Make a postman call with adding a slash to the end

Expected Output

Same answer whether it has a slash or not

Anything else?

No response
