Secured controller returns 403 one one action but not on another in Grails app - rest

Question

I have a controller in my app as follows:
#Secured(UserRoles.ROLE_USER)
class ProjectController implements BaseController, SpringSecurityAware {
ProjectService projectService
def create(ProjectCommand command) {
...
}
def update(ProjectCommand command) {
Long projectId = params.id
...
}
}
And it mapped as follows:
post "/v1/api/project" (controller: "project", action: "create")
put "/v1/api/project/$id" {
controller = "project"
action = "update"
constraints {
id(matches:/\\\d+/)
}
}
I am using spring security rest with a custom token storage. The authentication mechanism works properly, as it's been tested and run for a while already.
When I am sending the post request to create the project, everything works fine.
However, if I am trying to update the project I am getting 403 without even getting into the action method.
My request looks like this:
PUT /v1/api/project/12 HTTP/1.1
Authorization: Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1NiIsImtpZCI6Ik1qTTFPRGxETjBWR1FUQXlOa00wUkRoR056TkZSRGs1TlRFME1VVXlRa0ZDT0VFelJUazBRdyJ9....0qS2PUw8PQ

Notes:
UserRoles.ROLE_USER is a simple string
If I am debugging the request, the resolved user does have the expected authorities
What am I missing?
I suspect that there is something wrong with UrlMapping
UPDATE
Here is the debug log... It does not make much sense to me. It seems like it authenticated properly, but at the very end, the role was not allowed, even though it was the correct role.

Answer 1

Apparently, the problem was not related to security at all.
The issue was with the UrlMapping.
The UrlMapping for the update was supposed to be:
put "/v1/api/project/$id" {
controller = "project"
action = "update"
constraints {
id(matches:/\d+/)
}
}
The regex for constraints was wrong.
However, I still don't understand why 403 was returned and not 404.
