I was trying to add newly created product in shopping list and below error occurred when trying to save. I am using Grocy as add-on in Home Assistant.

Error source:

Error message:

Have you done a little tiny search beforehand and found #1900 and all the other referenced threads there?

You most likely managed to enter a non-number where a number is expected, for a shopping list item this can only be the amount field itself. It's not possible to enter such bullshit via the web frontend, but maybe via community contributed third party apps or something like that. Find the problematic item, fix it or restore your backup from a state where this wasn't a problem - just to name a few options.

In either case, nothing to track and fix here unless a 100 % reproducible example (only using Grocy) is provided.
