This is the same issue as this one (I’ll call it Form Episode 2) and this one (I’ll call it Form Episode 1). Unsurprisingly, it requires the same solution as the other 2 issues.
On page 216/217, the following code produces an error:
<.input field={{f, :user_id}} type="hidden" />
<.input field={{f, :product_id}} type="hidden" />
<.input field={{f, :stars}} type="rating" prompt="Rating"
options={["★★★★★": 5, "★★★★": 4, "★★★": 3, "★★": 2, "★": 1
]} />
The error reads:

To fix the error, change the offending lines to read:
<.input field={f[:user_id]} type="hidden" />
<.input field={f[:product_id]} type="hidden" />
<.input field={f[:stars]} type="rating" prompt="Rating"
options={["★★★★★": 5, "★★★★": 4, "★★★": 3, "★★": 2, "★": 1
]} />
