Description

As title says, it seems not possible to add a label to a PR through existing REST API. A /repos/{owner}/{repo}/pulls/{index} PATCH request using { "labels": [ 182 ] } as body (with that label being present for that repo) returns a 201 but the label is not added.

when using this approach xorm.log yields (selects omitted):

2018/11/30 13:21:31 [I] [SQL] UPDATE `webhook` SET `last_status` = ?, `updated_unix` = ? WHERE `id`=? []interface {}{1, 1543584091, 208}
2018/11/30 13:21:32 [I] [SQL] UPDATE `issue_user` SET is_read=? WHERE uid=? AND issue_id=? []interface {}{true, 5, 14879}
2018/11/30 13:22:30 [I] [SQL] UPDATE `issue` SET `repo_id` = ?, `index` = ?, `poster_id` = ?, `name` = ?, `content` = ?, `milestone_id` = ?, `priority` = ?, `is_closed` = ?, `is_pull` = ?, `num_comments` = ?, `ref` = ?, `deadline_unix` = ?, `closed_unix` = ?, `updated_unix` = ? WHERE `id`=? []interface {}{276, 215, 5, "test auto label", "testtesttesttesttesttest", 0, 0, false, true, 0, "", 0, 0, 1543584150, 14879}
2018/11/30 13:23:12 [I] [SQL] UPDATE `issue_user` SET is_read=? WHERE uid=? AND issue_id=? []interface {}{true, 5, 14879}

whereas, when manually adding the label to the PR, xorm.log shows (selects also omitted):

2018/11/30 13:19:03 [I] [SQL] UPDATE `webhook` SET `last_status` = ?, `updated_unix` = ? WHERE `id`=? []interface {}{1, 1543583943, 208}

2018/11/30 13:19:26 [I] [SQL] COMMIT

Current workaround is to use instead a PUT request to /repos/{owner}/{repo}/issues/{index}/labels using the same index and set the label on the PR through the issues endpoint

[lafriks]

I think there is already PR to fix this

[juanpablo-santos]

@lafriks, perhaps #5347?

[lafriks]

yes, closing as fixed
