Hi @rudolfbruder,
Since this is a paginated response. should the commit line read like this instead?
commit("SET_COLORED_PRODUCTS", response.data.data);
That is, you first need to access the response's data property, then the data property from the actual returned JSON which should contain (I assume) an array of coloured products.
From what I can see, I think response.data.colored_products would return undefined and perhaps that is causing other issues in the rest of your code.
