<!-- Answer -->
To resolve the error **{'message': {'json_metadata': [{'positions': ['Not a
valid mapping type.']}]}}**, you need to ensure that the `positions` key in the
`json_metadata` is correctly formatted as a valid mapping type (i.e., a
dictionary).
Here's how you can modify your code to ensure the `positions` key is
correctly formatted:
1. Fetch the `position_json` from the dashboard data.
2. Parse the `position_json` to ensure it is a valid dictionary.
3. Add the parsed `position_json` to the `json_metadata`.
Here's the updated code:
```python
import json
import requests
dashboard_id = 1
headers = {
"Content-Type": "application/json",
"Authorization": f"Bearer {self.access_token}",
"X-CSRFToken": self.csrf_token
}
# Fetch the dashboard data
dashboard_response =
requests.get(f"{superset_url}/api/v1/dashboard/{dashboard_id}",
headers=headers, cookies=self.cookies)
dashboard_data = dashboard_response.json()["result"]
# Extract and update json_metadata
json_meta = dashboard_data.get("json_metadata", "")
json_meta = json.loads(json_meta)
# Ensure positions is a valid mapping type
positions = dashboard_data.get("position_json", "{}")
positions = json.loads(positions) if isinstance(positions, str) else
positions
json_meta["positions"] = positions
# Prepare the request payload
request_payload = {
"dashboard_title": "intergrate_test",
"duplicate_slices": True,
"json_metadata": json.dumps(json_meta)
}
# Make the copy API call
r = requests.post(f'{superset_url}/api/v1/dashboard/{dashboard_id}/copy/',
json=request_payload, headers=headers,
cookies=self.cookies)
print(r.json())
```
This code ensures that the `positions` key is included in the
`json_metadata` as a valid dictionary, which should resolve the error
