Parsing parameters to express endpoint

Question

I have several express endpoints running which are querying a database. I'm trying to parse parameters in my express-gateway like this:

paths: ['/users', '/users/:userId']

The user endpoint is running on localhost and /users does return all users as intended. The problem is that /users/:userId also returns all users - it should only return one.

When i try to call the endpoint without the gateway it is working fine (http://localhost:3000/users/F692D717-F304-4D9B-A302-44F143923A93/)

But it's not working through the gateway. It seems like it never reaches the last endpoint or doesn't parse the parameter.

My gateway.config.yml:

http:
  port: 8080
admin:
  port: 9876
  hostname: localhost
apiEndpoints:
  users:
    host: "*"
    paths: ['/users', '/users/:userId']
  accounts:
    host: "*"
    paths: '/accounts'
  companies:
    host: "*"
    paths: '/companies'
serviceEndpoints:
  users:
    url: 'http://localhost:3000/users'
  accounts:
    url: 'http://localhost:3002/accounts'
  companies:
    url: 'http://localhost:3001/companies'
policies:
  - basic-auth
  - cors
  - expression
  - key-auth
  - log
  - oauth2
  - proxy
  - rate-limit
pipelines:
  users:
    apiEndpoints:
      - users
    policies:
      - proxy:
          - action:
              serviceEndpoint: users 
              changeOrigin: false
              ignorePath: true
  accounts:
    apiEndpoints:
      - accounts
    policies:
      - proxy:
          - action:
              serviceEndpoint: accounts 
              changeOrigin: false
              ignorePath: true
  companies:
    apiEndpoints:
      - companies
    policies:
      - proxy:
          - action:
              serviceEndpoint: companies 
              changeOrigin: false
              ignorePath: true

Answer 1

Found a solution. Under the proxy policy action for a given endpoint i need to set prependPath:false. I can't seem to find a reason inside the documentation.

Final gateway.config.yml:

 http:
  port: 8080
admin:
  port: 9876
  hostname: localhost
apiEndpoints:
  users:
    host: "*"
    paths: ['/users', '/users/:userId']
  accounts:
    host: "*"
    paths: '/accounts'
  companies:
    host: "*"
    paths: '/companies'
serviceEndpoints:
  users:
    url: 'http://localhost:3000/users'
  accounts:
    url: 'http://localhost:3002/accounts'
  companies:
    url: 'http://localhost:3001/companies'
policies:
  - basic-auth
  - cors
  - expression
  - key-auth
  - log
  - oauth2
  - proxy
  - rate-limit
pipelines:
  users:
    apiEndpoints:
      - users
    policies:
      - proxy:
          - action:
              serviceEndpoint: users 
              changeOrigin: false
              prependPath: false
  accounts:
    apiEndpoints:
      - accounts
    policies:
      - proxy:
          - action:
              serviceEndpoint: accounts 
              changeOrigin: false
              prependPath: false
  companies:
    apiEndpoints:
      - companies
    policies:
      - proxy:
          - action:
              serviceEndpoint: companies 
              changeOrigin: false
              prependPath: false

Have you tried to set ignorePath to false? That should do the trick or alternatively, just remove the option at all from the file since its default value is false
