1.4.13 self-hosted here, I added a string attribute to an existing collection, and it’s been given the status of “processing”. It doesn’t go away. Restarted the containers, and the attribute is there, but so is the processing commentary. I haven’t tried assigning any document a value to the attribute yet to see if it really works.
TL;DR
Developers on version 1.4.13 encountering an issue where newly added attribute in a collection is stuck on "processing" status. Restarting containers did not resolve the issue. Attribute is visible but processing status remains. Solution: Try assigning a value to the attribute to see if it works properly.
