If the method is not present, return the attribute values as a dictionary. * refactor: Update field serializer function and error handling in build_flow function * remove use memo to prevent bugs * feat: add updateMessagePartial method to MessagesStoreType * feat: update message partially in MessagesStoreType This commit adds the `updateMessagePartial` method to the `MessagesStoreType` in `messagesStore.ts`. This method allows updating a specific message by merging the changes with the existing message object. * feat: add log callback for start message in ChatComponent * feat: update log_callback name * feat: add log_callback for message in ChatComponent that are not streaming * refactor: remove console.log statement in buildFlowVertices function * refactor: store message in ChatInput after updating flow_id This commit refactors the `ChatInput` component by moving the logic to store the message after updating the `flow_id` property. This ensures that the message is properly stored in the correct flow. The previous implementation had the logic to store the message before updating the `flow_id`, which could lead to incorrect storage of messages. This change improves the reliability and accuracy of message storage in the `ChatInput` component. * refactor: move message storage logic in ChatInput after updating flow_id * refactor: update ChatComponent to use stored_message.id instead of self.graph.flow_id Update the `ChatComponent` class in `chat.py` to use the `stored_message.id` property instead of `self.graph.flow_id` when logging a message. This ensures that the correct message ID is used for logging purposes. The previous implementation used the flow ID, which could lead to incorrect logging. This change improves the accuracy of message logging in the `ChatComponent`. * refactor: remove unused code and console.log statements * raw: temp serializer fix * streaming working but the message comes in one shot * refactor: optimize message update in useMessagesStore Improve the efficiency of updating messages in the `useMessagesStore` function of `messagesStore.ts`. Instead of iterating through the entire message list, this refactor searches for the message to update by iterating backwards from the end. This approach allows for faster message retrieval and update. The code has been modified to use a for loop and break out of the loop once the message is found. This change enhances the performance of the message update process. * Refactor `serialize_flow_id` method to correctly handle UUID serialization in `message.py` * Refactor `send_event` method to use `jsonable_encoder` for data serialization * refactor: optimize message update in useMessagesStore * streaming working with timeout * refactor: update buildUtils.ts to use data instead of data.data in addMessage function * version with reactState for chatHistory * refactor: update on_message method in ChatComponent * refactor: update on_message method in ChatComponent * refactor: Remove unused dependency in package-lock.json * Refactor chatView component and add hiddenSession prop * Refactor chatView component and update hiddenSessions prop * Refactor chatView component to use visibleSessions prop instead of hiddenSessions * Refactor IOModal component to remove redundant code * Refactor chatView component to include focusChat prop * Refactor chatView component to include focusChat prop and trigger focus on chat when new session is set * Refactor IOModal component to update visible sessions when new session is added * feat: Add session parameter to buildFlowVertices function * feat: Add someFlowTemplateFields function Add the someFlowTemplateFields function to the reactflowUtils module. This function checks if any of the nodes in the provided array have template fields that pass a given validation function. * feat: Add session parameter to buildFlowVertices function * feat: Add session parameter to buildFlowVertices function * update Session logic on ioModal * Refactor ChatView component: Remove unused eraser button The eraser button in the ChatView component was removed as it was not being used and served no purpose. This change improves code cleanliness and removes unnecessary code. * Refactor Vertex class: Inject session_id if provided in inputs * Refactor build_flow function: Set default session if inputs are empty * Refactor InputValueRequest schema: Add session parameter * Refactor IOModal component: Update session logic * Refactor buildFlowVertices function: Update input handling * Refactor
