OpenCV keras model raises error "__init__() got an unexpected keyword argument 'ragged'"

While predicting from model using OpenCV I am encountering this error: __init__() got an unexpected keyword argument 'ragged'.

import os
import cv2
import numpy as np
from keras.models import model_from_json
from keras.preprocessing import image

cap = cv2.VideoCapture(0)
model = model_from_json(open("path of json model", "r").read())

The traceback:

TypeError: __init__() got an unexpected keyword argument 'ragged'

I am using Keras 2.3.1 and OpenCV 4.1.2.

I also tried replacing
from keras.models import model_from_json with
from tensorflow.keras.models import model_from_json
with no improvement.
