I cannot create new issue through with REST API

Question

I'm troubled with redmine.

When I create new issue with Rest API(from Microsoft Excel), Internal Error 500 happened. Seeing from production.log, "NoMethodError" is happened (see below message)

Started POST "/redmine/issues.xml?key=XXXXXXX" for XX.XX.XX.XXX at 2016-05-30 14:44:10 +0900

So, I tried to create new issew using web browser (IE11). The ticket was created normally. Here is production.log.

I already tried to migrate, clear cache. What should I do next.

Here is my environment on RHEL7.2

Environment:
  Redmine version                3.2.0.stable
  Ruby version                   2.2.4-p230 (2015-12-16) [x86_64-linux]
  Rails version                  4.2.5
  Environment                    production
  Database adapter               Mysql2
SCM:
  Subversion                     1.7.14
  Git                            1.8.3.1
  Filesystem                     
Redmine plugins:
  redmine_export_with_journals   0.0.8
  redmine_importer               1.2.2
  redmine_local_avatars          1.0.0
  redmine_xlsx_format_issue_exporter 0.1.2
  sidebar_hide                   0.0.7

Here is assinable_versions source-code

# Versions that the issue can be assigned to
def assignable_versions
  return @assignable_versions if @assignable_versions

  versions = project.shared_versions.open.to_a #Here is line823

  if fixed_version
    if fixed_version_id_changed?
      # nothing to do
    elsif project_id_changed?
      if project.shared_versions.include?(fixed_version)
        versions << fixed_version
      end
    else
      versions << fixed_version
    end
  end
  @assignable_versions = versions.uniq.sort
end

The error is occurring in app/models/issue.rb where you are calling 'shared_versions' method with an object of nil class. Check your app/models/issue.rb at line number 823. — Prity, May 31 '16 at 08:02
Thanks Prity! Of cource I've checked at line 823 on issue.rb. — Tomoya Katsuki, Jun 01 '16 at 01:47
Here is the code. **#Versions that the issue can be assigned to def assignable_versions versions = project.shared_versions.open.to_a (<- line 823)** And then I've checked project.rb, "def shared_versions" exist. After that I add nil judgement before line 823 of issue.rb. , like this. **# Add Nil Judgement if !project.shared_versions.nil? versions = project.shared_versions.open.to_a end** But same error happens on nil judgment line. — Tomoya Katsuki, Jun 01 '16 at 01:56
Thanks, here ls source code. ` # Versions that the issue can be assigned to def assignable_versions return @assignable_versions if @assignable_versions versions = project.shared_versions.open.to_a #Here is line823 if fixed_version if fixed_version_id_changed? # nothing to do elsif project_id_changed? if project.shared_versions.include?(fixed_version) versions << fixed_version end else versions << fixed_version end end @assignable_versions = versions.uniq.sort end` — Tomoya Katsuki, Jun 06 '16 at 06:50

The error is occurring because project is nil and you are trying to call nil.shared_versions. So change the if condition:

if !project.shared_versions.nil? 
  versions = project.shared_versions.open.to_a 
end

to as follows:

versions = project.shared_versions.open.to_a unless project.nil?

This will resolve the 'undefined method' error.

Thanks! I've changed Nil judgement as you said. The "undefined method error" at line 823 is disappeared! But trouble has been continued. – Tomoya Katsuki Jun 02 '16 at 12:20
@Tomoya Katsuki I think you should check your code that why project = nil ? Please share complete code of 'assignable_versions' method in issue.rb – Prity Jun 02 '16 at 12:24
Thanks @Prity. Please see original Question text. I added assignable_version source code. – Tomoya Katsuki Jun 08 '16 at 01:14

I've solved problem. There is some difference of REST process.

At least redmine 2.4.4, I can use both project_id = identifier and project_id = project_id for issue create.

But, redmine 3.x, I can only use project_id = project_id for issue create.
