Optional cloze card possible?

Anki Desktop
1

I have a normal cloze note like this:

Meaning:
the powdery residue left after the burning of a substance

Word:
ash

Example:
cigarette {{c1:ash}}

Which can produce a card like this

Front:
the powdery residue left after the burning of a substance
cigarette [...]
| an input box for the word "ash" |

Back:
the powdery residue left after the burning of a substance
cigarette ash
ash

The clozed example sentences serve as a very good hint, but for some words I don’t need such hint. When the Example field is empty, Anki complains that “No cloze ⁨1⁩ found on card”. I know this refers to the situation where you previously had created a c2 cloze and then removed it. But in my case all fields don’t contain the {{}} placeholder. Is it possible to make Anki turn off warning for such cards?

The working is when there is no {{}} on the card i.e. no clozes when using a cloze note type. What I do suggest is using the built in cloze hint functionality. You need to add two colons followed by the text you want to hint.

Following your example:
the powdery residue left after the burning of a substance {{c1::cigarette::an input box for the word "ash"}}
