b-form-invalid-feedback不适用于Vuelidate

Question

在插入2个或更少的字符时，我似乎似乎没有显示 b-form-invalid-feedback 块。我正在使用Vuejs和Bootstrap-vuejs（Bootstrap-vue）：

html：

<b-form @submit="onSubmit">
                        <b-form-group id="fieldsetHorizontal" horizontal :label-cols="4" breakpoint="md" label="Emri">
                            <b-form-input id="name"
                            v-model.trim="patient.name"
                            :state="$v.patient.name.$dirty ? !$v.patient.name.$error : null"
                            aria-describedby="input-1-live-feedback">
                            </b-form-input>

                            <b-form-invalid-feedback id="input-1-live-feedback">
                              This is a required field and must be at least 3 characters
                            </b-form-invalid-feedback>

                        </b-form-group>
</b-form>

脚本：

validations: {
        patient: {
            name: {
                required,
                minLength: minLength(3)
            }
        }
    },
