I have a similar issue.
I have tested the API on one of the repositories and since it worked I have integrated jenkinsapi in my script.
Later on turned out it doesn't work on different repository.
The difference I could see regarding the artifacts is that on See fingerprints, the Original owner is defined as this build for all files, while on the not working job I have outside Jenkins, even though it was created on a different branch.

filename and hash are correct in the {URL}/fingerprint/{md5}/python/api, but the original field instead of having reference to another build says "original": None.

The branch where it was first generated is already removed in git, so the build job is also removed and this verification probably fails for this reason.
