Vuetify Select with options array of objects prevents update from occurring?

Question

I've got a doughnut chart being displayed using vue-chartjs and am supplying color schemes via chartjs-plugin-colorschemes.

I'm working on the ability for the user to switch out color schemes and persist their chosen scheme to the db, however I've run into an odd issue. When adding a colors array to the options that are being supplied to the Vuetify select, it breaks the chart from updating to the new color scheme. I've narrowed it down to this specifically, because if I remove the colors array from options, it correctly updates the chart (however then I'm not able to display the colors like I'm trying to do in the select dropdown).

Why would adding properties to the Vuetify select break this functionality? Is it because they're being dynamically generated?

Answer 1

On a Hail Mary attempt, I found something in the chartjs-plugin-colorschemes docs that mentioned setting override: true within the color schemes object on data. Adding that fixed it somehow!

plugins: {
  colorschemes: {
    scheme: this.theme,
    override: true
  }
},
