"Review can not be requested from author"

[Warchant]

4 developers work on a single repo. If one developer creates a PR, and he is in the "reviewers" list, action fails with "Review can not be requested from author".

Expected behavior:
Author is skipped, all other users added as reviewers.

Actual behavior:
0 reviewers added.

Config:

# Set to true to add reviewers to pull requests
addReviewers: true

# Set to author to set pr creater as assignee
addAssignees: author

# A list of reviewers to be added to pull requests (GitHub user name)
reviewers:
  - deva
  - devb
  - devc
  - devd

# A number of reviewers added to the pull request
# Set 0 to add all the reviewers (default: 0)
numberOfReviewers: 0

# A list of keywords to be skipped the process that add reviewers if pull requests include it
skipKeywords:
  - wip

Hi @Warchant ! Thanks for reporting the problem.

The message Review can not be requested from author is shown, when the PR author is added as a reviewer to the pull request. This behavior is specification on GitHub.

Auto Assign Action excludes the PR author from reviewers. I checked your repository. I have a concern that a format of reviewer list may have caused the exclusion process to fail.

I want you to try modifying to Warchant from warchant in the reviewers' list.

Usernames must be handled in lowercase on the application. I think to need to fix it.

Had the same issue in a private repo run, different casing was indeed the problem in my case;

# A list of reviewers to be added to pull requests (GitHub user name)
reviewers:
  - deva
  - devb
  - devc
  - devd

# A number of reviewers added to the pull request
# Set 0 to add all the reviewers (default: 0)
numberOfReviewers: 0

where the user that commits has a username "Deva" results in this behaviour. Changing it to:

# A list of reviewers to be added to pull requests (GitHub user name)
reviewers:
  - Deva
  - devb
  - devc
  - devd

# A number of reviewers added to the pull request
# Set 0 to add all the reviewers (default: 0)
numberOfReviewers: 0

Fixes the issue.

As all other username functionality on github is case insensitive this is counter-intuitive and I had to come here to see this as well, maybe this can be changed to accept any case variant?
