how can i pass on parameters through /v1/process

[phoenix-lee-tpe]

where and how should i put parameters so they will be passed on to the langflow components in specified in my flow? try "parameters" & "artifacts" in data field, all failed...

Hello @phoenix-lee-tpe! I'm Dosu, a friendly bot here to assist you with your questions, help squash bugs, and guide you through contributing to projects. While we wait for a human maintainer, I'll do my best to streamline the process for you. Let's dive right into it!

To pass parameters to the langflow components in your flow through /v1/process, you can use the sendAll function. This function sends data to the API for prediction. Here is the function definition:

/**
 * Sends data to the API for prediction.
 *
 * @param {sendAllProps} data - The data to be sent to the API.
 * @returns {AxiosResponse<any>} The API response.
 */
export async function sendAll(data: sendAllProps) {
  return await api.post(`${BASE_URL_API}predict`, data);
}

You can pass the parameters as an object to the sendAll function. The object should match the sendAllProps type. Here is an example of how you might use this function:

const data = {
  // Fill this object with your parameters
  param1: value1,
  param2: value2,
  // ...
};

sendAll(data)
  .then(response => {
    // Handle the response
  })
  .catch(error => {
    // Handle the error
  });

Please replace param1, value1, param2, value2, etc. with your actual parameters and values. The sendAllProps type in the langflow codebase is structured as follows:

export type sendAllProps = {
  nodes: Node[];
  edges: Edge[];
  name: string;
  description: string;
  viewport: Viewport;
  inputs: { text?: string };
  chatKey: string;
  chatHistory: { message: string | object; isSend: boolean }[];
};

Here is a breakdown of its structure:

• nodes: An array of Node objects.
• edges: An array of Edge objects.
• name: A string representing the name.
• description: A string representing the description.
• viewport: An object of type Viewport.
• inputs: An object that may contain a text property of type string.
• chatKey: A string representing the chat key.
• chatHistory: An array of objects, each containing a message property that can be a string or an object, and an isSend property of type boolean.

Unfortunately, I wasn't able to find any specific requirements or constraints for the parameters that can be passed to the langflow components through the /v1/process endpoint within the repository. If you could provide more details about the parameters you're trying to pass and the issues you're encountering, I might be able to provide a more specific solution.

You can find more details about the sendAll function and the sendAllProps type in the API controller and the API types respectively.
