Error code 422 Unprocessable Entity, When Running cURL Code for Langflow Flow with TWEAKS about langflow

[dosubot]

To resolve the 422 Unprocessable Entity error when running a cURL request for a Langflow flow with tweaks, ensure that the JSON payload you are sending matches the expected schema defined in the TweaksRequest class. The tweaks field should be a dictionary where the keys are strings and the values are dictionaries with string keys and any type of values.

Here is an example of how you can structure your cURL request:

curl -X POST "http://127.0.0.1:7860/api/v1/run/test_endpoint?stream=false" \
     -H "Content-Type: application/json" \
     -d '{
           "input_value": "message",
           "input_type": "chat",
           "output_type": "chat",
           "tweaks": {
             "OpenAIModel-NIWAF": {
               "input_value": "",
               "max_tokens": 3000,
               "model_kwargs": {"response_format": {"type": "json_object"}},
               "model_name": "gpt-3.5-turbo",
               "openai_api_key": "OPEN_AI_EJ_KEY",
               "stream": false,
               "temperature": 0.2
             },
             "ChatOutput-cctL9": {
               "record_template": "{text}",
               "return_record": false,
               "sender": "Machine",
               "sender_name": "AI"
             },
             "ChatInput-sQJ5q": {
               "input_value": "hi",
               "return_record": false,
               "sender": "User",
               "sender_name": "User"
             },
             "Prompt-uGsOk": {
               "template": "\nYou are a pirate:\nreply as json\n{user_input}\n",
               "user_input": ""
             },
             "TextOutput-9Nuat": {
               "input_value": "",
               "record_template": ""
             },
             "ChatOutput-dfQkZ": {
               "record_template": "{text}",
               "return_record": false,
               "sender": "Machine",
               "sender_name": "AI"
             }
           }
         }'

Ensure that the JSON structure matches the TweaksRequest schema:

class TweaksRequest(BaseModel):
    tweaks: Optional[Dict[str, Dict[str, Any]]] = Field(default_factory=dict)

If the structure of your JSON payload does not match this schema, the server will return a 422 Unprocessable Entity error. Additionally, make sure to include the required headers such as Content-Type as shown in the example.

This should help you resolve the issue and successfully run the cURL request with tweaks ^[1][2][3][4].
