Nutri-score-grade error inadvertently triggered

[aleene]

What

A product belonging to the olive oils category AND olive oil as ingredient triggers an error en:Nutri-score-grade-from-category-does-not-match-calculated-grade. There is no grade calculated, so why?

Steps to reproduce the behaviour

see https://nl.openfoodfacts.org/product/8718907514255/extra-vierge-olijfolie-albert-heijn-bio

Expected behaviour

There is no actual error, just lacking data. So no error expected. By the way the nutriscore can be forced through ingredients and/or category.

Why

This should not trigger a nutriscore error as it can not be repaired. The corresponding state for lacking nutritional data is sufficient (which might be used to suppress the error.

[benbenben2]

It expects grade C and the product has no grade (no picture for nutrition table, hence not possible to add the data).

Technically, the error is correct. But practically, it cannot be fixed without having a picture of the table.

Hence, suggested solution: do not trigger the error if:

• nothing is entered in the nutrition table, or
• "Nutrition facts are not specified on the product." is checked
