Description

app/pages/login.vue:70:8 - error TS2322: Type '(payload: FormSubmitEvent<{ email: string; password: string; rememberMe: boolean; }>) => Promise<void>' is not assignable to type '(((() => void) | ((event: FormSubmitEvent<{ email: string; password: string; rememberMe: boolean; }>) => void)) & ((payload: FormSubmitEvent<{ email: string; password: string; rememberMe?: boolean | undefined; }>) => any)) | undefined'.
  Type '(payload: FormSubmitEvent<{ email: string; password: string; rememberMe: boolean; }>) => Promise<void>' is not assignable to type '(() => void) & ((payload: FormSubmitEvent<{ email: string; password: string; rememberMe?: boolean | undefined; }>) => any)'.

      Target signature provides too few arguments. Expected 1 or more, but got 0.

           ~~~~~~~~
    The expected type comes from property 'onSubmit' which is declared here on type 'NonNullable<VNodeProps & AllowedComponentProps & ComponentCustomProps & { as?: any; icon?: any; title?: string | undefined; description?: string | undefined; ... 21 more ...; novalidate?: Booleanish | undefined; } & Record<...>>'

//                                                                  ^^^^^^^^^^^^
