New importing feature causes error after importing file with duplicates

I was testing out the beta importing feature, but it seems to have a problem with handling duplicate cards, especially when the “Existing cards” option is left on the default “Update” in the import dialog.

When importing a file with a note that already exists in the deck, Anki claims it skipped the duplicate, but it adds a “ghost card” to the schedule, and when studying, gives the following error when the review comes up:

An error occurred. Please use Tools > Check Database to see if that fixes the problem.
If problems persist, please report the problem on our support site. Please copy and paste the information below into your report.
Anki 2.1.54 (b6a7760c) Python 3.9.7 Qt 6.3.1 PyQt 6.3.1
Platform: Windows 10
Flags: frz=True ao=False sv=2
Add-ons, last update check: 2022-08-29 14:19:54

Caught exception:

Steps to reproduce:

  1. Create a CSV file with a single line:
  1. On a fresh profile with the new importing option enabled, import the file, keeping the options on default.
  2. Import the same file again.

Now the “ghost card” will appear as a new card.

Running Tools > Check database actually fixes the problem with the message that a card with a missing note was removed.


Thanks for the report. This happens to be already fixed as a side effect of this:
