unable to export a project from gitlab

Hi,

We are using GitLab Community Edition 9.5.9. We are unable to export project neither from UI, nor using API nor from console.

From UI - No export link is send to mail or download export option is not available. We have waited long.

Using API - see below error

# curl --request POST --header  "Private-Token: XXXX" https://gitlab.host.sxt.com/api/v4/projects/6372/export --data "description=FooBar&upload[http_method]=PUT&upload[url]=https://localhost/"
{"error":"404 Not Found"}

# curl --header  "Private-Token: XXXXX" https://gitlab.host.sxt.com/api/v4/projects/6372/export
{"error":"404 Not Found"}

From console - See below

# gitlab-rails console
Loading production environment (Rails 4.2.8)
irb(main):001:0> group = Group.find_by_full_path("trx/trx")
=> nil
irb(main):002:0> group = Group.find_by_full_path("trx")
=> #<Group id:5895 @trx>
irb(main):003:0> admin_user = User.find_by(username: "dthankac")
=> #<User id:138 @dthankac>
irb(main):005:0> group.projects.each do |project|
irb(main):006:1* puts "Executing export for #{project.full_path}"
irb(main):007:1> exporter = Projects::ImportExport::ExportService.new(project, admin_user)
irb(main):008:1> exporter.execute
irb(main):009:1> end; nil
