This issue started occurring today.


If you try to post a comment to a PR and don't specify the line, CommitComment uses a line of 0, and github now returns an error.

Groovy code snippet:

    CommitComment commitComment = new CommitComment()
    commitComment.setCommitId(commitId)
    commitComment.setPath("path/to/file.kt")
    commitComment.setPosition(36)
    commitComment.setBody("Hello there")

    def gitHubClient = new GitHubClient()
    gitHubClient.setOAuth2Token(token)
    def repositoryId = new RepositoryId(orgName, repoName)
    def pullRequestService = new PullRequestService(gitHubClient)
    def pullRequestId = 123
    pullRequestService.createComment(repositoryId, pullRequestId, commitComment)

This fails with:

Caused by: org.eclipse.egit.github.core.client.RequestException: Validation Failed (422): line required and an integer greater than zero
        at org.eclipse.egit.github.core.client.GitHubClient.createException(GitHubClient.java:606)
        at org.eclipse.egit.github.core.client.GitHubClient.sendJson(GitHubClient.java:697)

        at MyScript.postPrComment(/path/to/MyScript.gradle:65)

If you add commitComment.setLine(someLine), it works.

Note that if you use the curl apis, you can either leave the line out altogether, or specify a non-zero line. But, in curl, if you specify a line of 0, it also fails.


Works (no line):
curl --request POST -H "Content-Type: application/json" -H "Authorization: token "sometoken" https://api.github.com/repos/orgName/repoName/pulls/123/comments --data '{"body":"hello world","path":"path/to/file.kt","position":3, commit_id":"1234567"}'


Doesn't work anymore (line is 0):
curl --request POST -H "Content-Type: application/json" -H "Authorization: token "sometoken" https://api.github.com/repos/orgName/repoName/pulls/123/comments --data '{"body":"hello world","path":"path/to/file.kt","position":3, "commit_id":"1234567", "line":0}'
