I am working on a application based on false i have to display end date.
my schema:
export const experienceSchema = yup.object().shape({
    experience: yup.string().required(),
    job_title: yup.string().required(),
    category: yup.string().required(),
    current_working_status: yup.string().required(),
    join_date: yup.date().required(),
    end_date: yup
        .date()
        .notRequired()
        .when('current_working_status', {
            is: 'false',
            then: yup.date().required('Please enter date'),
        }),
});
my html:
<div className="mt-2">
    <label className="fw-medium">
        Currently Working<sup>*</sup>
    </label>
    <div className="input-group">
        <select
            className="form-select"
            id="select-example"
            name="current_working_status"
            onChange={formik.handleChange}
            onBlur={formik.handleBlur}
            value={formik.values.current_working_status}>
            <option value="">Select an option</option>
            <option value={true}>Yes</option>
            <option value={false}>No</option>
        </select>
    </div>
    {formik.touched.current_working_status && formik.errors.current_working_status ? <div className="edit_error">{formik.errors.current_working_status}</div> : null}
</div>
<div className="d-md-flex justify-content-between my-3">

                className="form-control"
                placeholder="join_date"
                onChange={formik.handleChange}
                onBlur={formik.handleBlur}
                value={formik.values.join_date}
            />
        </div>
        {formik.touched.join_date && formik.errors.join_date ? <div className="edit_error">{formik.errors.join_date}</div> : null}
    </div>
    {formik.values.current_working_status !== 'true' ? (
        <div className=" col-md-5">

                    className="form-control"
                    placeholder="end_date"
                    onChange={formik.handleChange}
                    onBlur={formik.handleBlur}
                    value={formik.values.end_date}
                />
            </div>
            {formik.touched.end_date && formik.errors.end_date ? <div className="edit_error">{formik.errors.end_date}</div> : null}
        </div>
    ) : (
        ''
    )}
</div>
if user select currently working on yes, i just want to use join date, if select no i want use both join and end date. vice versa i want to validate.
When i select on no i am getting error as :
branch is not a function
TypeError: branch is not a function
Kindly please help me at this problem.
Using conditional validation i have inserted code still i am unable to work on it.
