Bug: quantity unit stock has no values to choose

The iOS Grocy app managed to create products with no default purchase unit. This renders a given product unchangeable, as only the purchase unit Dropdown has any values to choose. Since both are mandatory fields, the product can’t be updated/fixed.

I was able to populate the Dropdown by creating a dummy conversation. The save was allowed but after a refresh, the issue reappeared. The PUT request is logged with status code 400. PHP error log is quiet, even though if set the level to debug for php-fpm.

since I don’t know how the app managed to create it in the first place, I can’t fully reproduce either.

this is one of the affected products retrieved via the API

A product always needs to have a Default quantity unit purchase, so creating one (however) without one or maybe delete the selected unit afterwards leads to bullshit without real surprise.

grocy is generally based around GIGO, so not a “bug”.
