Error when converting .onnx to tensorflow lite

I want to convert an .onnx file to tflite file but it is giving me this error .

AttributeError: module 'tensorflow.python.framework.type_spec' has no attribute '_NAME_TO_TYPE_SPEC'

here is my code:

import os
import onnx
from onnx_tf.backend import prepare

# Define input and output paths
input_path = "model.onnx"
output_path = "output_model"

try:
    # Check if input file exists
    if not os.path.exists(input_path):
        raise FileNotFoundError(f"ONNX model not found at: {input_path}")

    # Load the ONNX model
    onnx_model = onnx.load(input_path)
    tf_rep = prepare(onnx_model)
    tf_rep.export_graph(output_path)
    print("Conversion completed successfully!")
    
except Exception as e:
    print(f"Error during conversion: {e}")
    raise
