Does status/build throttle with 404s?

The jenkins bitbucket-pullrequest-builder plugin is using this api call:

https://developer.atlassian.com/bitbucket/api/2/reference/resource/repositories/{username}/{repo_slug}/commit/{node}/statuses/build/{key}

I am receiving errors like this from the endpoint, and I know that the build and commit both exist, and can be seen in the activity log from bitbucket:

Jan 29, 2019 6:49:01 PM bitbucketpullrequestbuilder.bitbucketpullrequestbuilder.bitbucket.ApiClient send WARNING: Response status: HTTP/1.1 404 Not Found URI: https://bitbucket.org/api/2.0/repositories/ACCT/REPO/commit/SH_HASH/statuses/build/jenkins-HASH
Jan 29, 2019 6:49:01 PM bitbucketpullrequestbuilder.bitbucketpullrequestbuilder.bitbucket.ApiClient send WARNING: {"type": "error", "error": {"message": "Build status with key 'jenkins-HASH' for node HASH repository REPO not found"}}

The behavior is sporadic - I see it from several different repos in our jenkins log file. The repos and hashes absolutely exist, so, I’m wondering if maybe I’m hitting throttling or something.

Hello,
None of the Bitbucket Cloud API endpoints return 404 for rate limiting. This is probably best to move to a support ticket so we can track down the problem for you.
