IAM: Token introspect returns error 500 for unknown tokens

[reinkrul]

E.g.:

POST http://localhost:1323/internal/auth/v2/accesstoken/introspect
Content-Type: application/x-www-form-urlencoded
Content-Length: 9
Connection: Keep-Alive
User-Agent: Apache-HttpClient/4.5.14 (Java/17.0.9)
Accept-Encoding: br,deflate,gzip,x-gzip

token=123

returns:

HTTP/1.1 500 Internal Server Error
Content-Type: application/problem+json
Vary: Origin
Date: Tue, 06 Feb 2024 16:11:28 GMT
Content-Length: 74

{
  "detail": "not found",
  "status": 500,
  "title": "IntrospectAccessToken failed"
}

I'd expect a response according to RFC7662 (active field)
