Issue Summary

Trying to move a list to a board that's set to read-only results in an error message, even though the list is actually moved.

Steps to Reproduce

1. Create a list with a few cards on it.
2. Move the list from Board 1 to Board 2 (which is set to read-only).
3. You will see an error message "Unable to move list". However, the list and its cards will actually be moved to Board 2 despite this error.
4. Secondary move (optional): If you try moving the list again (to Board 3 for example), you might see a success message "Moved (list name) to (Board 3)" but the list will appear empty.

Expected Results

The list is successfully moved to the read-only board (Board 2) with no error message, or the error message can be displayed but prevent the list from being moved.

Actual Results

• An error message appears stating "Unable to move list" even though the list and its cards are actually moved to the read-only board (Board 2). This can be confusing.
• If the user attempts to move the list again (to Board 3 for example) after encountering the error, they might see a success message but the list will appear empty.

Workaround

1. Go to Board 2 (the read-only board). You should see the list and its cards there.
2. If you need to move the list, you have two options:
   • Activate your free trial to move the list yourself.
   • Contact Trello support for assistance with moving the list.
