I added following live view template from scratch.
Please be noted that it has bad <:action> slot tag (should be <:actions> in plural form
<.header>
새봄맞이 대 할인 이벤트!
<:subtitle> 10% 싸게 해줄께요~ </:subtitle>
</.header>
<div>
<.simple_form
for={@form}
id="promo-form"
phx-change="validate"
phx-submit="save"
>
<.input field={@form[:first_name]} type="text" label="First Name" />
<.input field={@form[:email]} type="email" label="Email" />
<:action>
<.button>신청하기</.button>
</:action>
</.simple_form>
</div>
Above template produce following error message
[error] GenServer #PID<0.3845.0> terminating
** (FunctionClauseError) no function clause matching in Plug.CSRFProtection.get_csrf_token_for/1
...
That error message made me have hard time in fixing typo in template.
Why such error message is displayed?
