If you are running your own VersionEye instance since more than 4 weeks then you might see a message like this in the UI:
“Meta information about the project dependencies are currently fetched from the public VersionEye API. Currently fetching meta data for undefined.”
docker exec -it mongodb bash mongo use veye_enterprise; db.sync_statuses.dropIndex("obj_type_id_index"); exit exit
That will remove the index and fix the problem permanently. A new index with the same name will be created automatically in the next 24 hours, from a background job.
