Problem you have encountered:
As per the REST documentation here:  https://cloud.google.com/compute/docs/reference/rest/v1/urlMaps in the section
pathMatchers[].headerAction.responseHeadersToRemove[] it should be possible to remove headers from responses in any circumstance (i.e. both backend buckets and backend services). However, in the case of backend buckets this doesnt actually work.

Support suggested I raise this as a feature request, but I am raising it as a bug since the docs say its possible. Feel free to see this as a bug against the docs and then a feature to make it work.

What you expected to happen:
For Header actions to work with backend buckets.


Steps to reproduce:
Upload a YAML definition as follows (names are example):
name: gumwe001
description: 'URL Map for the assets site (both SSL and none)'
defaultService: https://www.googleapis.com/compute/v1/projects/website-xxxxxxxx/global/backendBuckets/gbbwe001
hostRules:
- hosts:
  - '*'
  pathMatcher: assets-pm
  description: 'Match All Hosts'
kind: compute#urlMap
pathMatchers:
- name: assets-pm
  defaultService: https://www.googleapis.com/compute/v1/projects/website-xxxxxxx/global/backendBuckets/gbbwe001
  pathRules:
  - paths:
    - /
    service: https://www.googleapis.com/compute/v1/projects/website-xxxxxxxxx/global/backendBuckets/gbbwe001
    routeAction:
      urlRewrite:
        pathPrefixRewrite: /index.html
  - paths:
    - /*
    service: https://www.googleapis.com/compute/v1/projects/website-xxxxxx/global/backendBuckets/gbbwe001
  - paths:
    - /test-redir
    urlRedirect:
      hostRedirect: www.google.com
      pathRedirect: /images
      redirectResponseCode: 'TEMPORARY_REDIRECT'
      httpsRedirect: true
      stripQuery: true
  headerAction:
    responseHeadersToRemove:
    - 'x-goog-generation'
    - 'x-goog-metageneration'
    - 'x-goog-stored-contentencoding'
    - 'x-goog-stored-content-length'
    - 'x-goog-meta-goog-reserved-file-mtime'
    - 'x-goog-hash'
    - 'x-goog-storage-class'
    - 'Server'
headerAction:
  responseHeadersToRemove:
  - x-goog-generation
  - x-goog-metageneration
  - x-goog-stored-contentencoding
  - x-goog-stored-content-length
  - x-goog-meta-goog-reserved-file-mtime
  - x-goog-hash
  - x-goog-storage-class
  - Server
tests: []

This will not work.

Other information (workarounds you have tried, documentation consulted, etc):

Note that a workaround was suggested by support to use routeRules - however routeRules dont work with backend buckets. Another solution would be to allow routeRules with backend buckets.
