I'm exporting dashboard objects from an existing workspace to new workspace but after importing ,the underlying dashboards data is not coming to new workspace. I'm using the below code. Can anyone help

import os
import requests
import json
import logging

log_file = 'import_dashboards_log.log'
logging.basicConfig(filename=log_file, level=logging.INFO,

target_workspace_url = 'https://.azuredatabricks.net'
target_workspace_token = 'dapib2e-3'

"""Create a folder in the Databricks workspace if it doesn't exist."""
url = f'{workspace_url}/api/2.0/workspace/mkdirs'
headers = {"Authorization": f"Bearer {token}", "Content-Type": "application/json"}
payload = {"path": folder_path}
response = requests.post(url, headers=headers, data=json.dumps(payload))
if response.status_code == 200 or response.status_code == 400: # 400 means folder already exists
logging.info(f"Folder created or already exists: {folder_path}")
print(f"Folder created or already exists: {folder_path}")
else:
logging.error(f"Failed to create folder {folder_path}. Error: {response.content}")
print(f"Failed to create folder {folder_path}. Error: {response.content}")

def import_dashboard(workspace_url, token, file_path, folder_path):
"""Import a dashboard JSON file into the new workspace."""
with open(file_path, 'r') as f:
dashboard_data = json.load(f)

# Prepare the import payload based on the provided JSON sample
import_dashboards = {
"name": dashboard_data.get('name'),
"parent": folder_path,
"tags": dashboard_data.get('tags', []),
"options": dashboard_data.get('options'),
"widgets": dashboard_data.get('widgets'),
"user": dashboard_data.get('user')
}

url = f'{workspace_url}/api/2.0/preview/sql/dashboards'
headers = {"Authorization": f"Bearer {token}", "Content-Type": "application/json"}
response = requests.post(url, headers=headers, data=json.dumps(import_dashboards))
