Steps to Reproduce:
This issue has come up on multiple development instances I've set up (using MW Docker Dev), but I have not encountered it in production.
- Import an item into your local Wikibase instance using WikibaseImport. I was attempting to import item Q62, San Francisco.
- Attempt to add the item by typing in the Depicts input box until it appears in the dropdown
- Click publish
Actual Results:
The panel displays the following error message:
This error also is displayed when attempting to add a Wikibase item that was created locally (not through import script).
Additionally, clicking "Cancel" to leave edit mode does not get the panel out of its broken state; the input field remains greyed out and disabled:
Clicking "Edit" again does not remedy this.
Expected Results:
The statement should publish normally.
