Looking at the error message, the issue appears to be a validation error where the webhook is expecting a string payload but receiving a dictionary. The specific error is:
Copy code
Input should be a valid string [type=string_type, input_value={'data': [...]}, input_type=dict]
To fix this, you'll need to modify your webhook template to properly handle the JSON payload. Here are two approaches: 1. If you're using a Prefect webhook block, you can add a template that converts the dictionary to a string:
Copy code
python
from prefect.blocks.webhook import Webhook

webhook = Webhook(
    url="your_webhook_url",
    template="""
    {
        "event": "pim.unifyd.catsy",
        "resource": {
            "prefect.resource.id": "pim.unifyd.catsy.handle",
            "payload": {{ json.dumps(body) }}
        }
    }
    """
)
2. If you're using the webhook directly in a flow, you can format the payload like this:
Copy code
python
import json
from prefect import flow
import httpx

@flow
def send_webhook():
    payload = {
        "event": "pim.unifyd.catsy",
        "resource": {
            "prefect.resource.id": "pim.unifyd.catsy.handle",
            "payload": json.dumps(your_data)  # Convert the data dict to a JSON string
        }
    }
    
    response = <http://httpx.post|httpx.post>("your_webhook_url", json=payload)
    return response
The key change is using 
json.dumps()
to convert the nested data dictionary to a string, which should satisfy the validation requirements of the receiving endpoint. Also, make sure your webhook endpoint is configured to accept and parse JSON payloads by setting the appropriate content-type header:
Copy code
python
headers = {
    "Content-Type": "application/json"
}
Let me know if you need help implementing either of these approaches or if you're using a different webhook configuration method.
