Hello @sorenaakjaer! I'm here to help you with any bugs, questions, or contributions you have for the Langflow repository. Let me know how I can assist you!
The error you're encountering with the "ChatInput" and "ChatOutput" components in Langflow is due to validation issues with the Message
class. Specifically, the text
field in the Message
class is not being recognized as a valid string, and there are additional checks for AsyncIterator
and Iterator
types.
To resolve this issue, ensure that the text
field in the Message
class is correctly formatted as a string. Here are the key points to check:
-
Ensure
text
is a String: Thetext
field should be a valid string. If it's not, you need to convert it to a string before passing it to theChatOutput
component. -
Validation Rules: The
Message
class has specific validation rules to ensure thetext
field is not anAsyncIterator
orIterator
. Here is the relevant code snippet for theMessage
class:@field_serializer("text", mode="plain") def serialize_text(self, value): if isinstance(value, AsyncIterator): return "" elif isinstance(value, Iterator): return "" return value
-
Correct Parameters: Ensure that the parameters passed to the
build
method of theChatOutput
component are correctly provided and match the expected types. Here is the relevant code snippet for theChatOutput
component:from typing import Optional, Union from langflow.base.io.chat import ChatComponent from langflow.field_typing import Text from langflow.schema import Record class ChatOutput(ChatComponent): display_name = "Chat Output" description = "Display a chat message in the Interaction Panel." icon = "ChatOutput" def build( self, sender: Optional[str] = "Machine", sender_name: Optional[str] = "AI", input_value: Optional[str] = None, session_id: Optional[str] = None, return_record: Optional[bool] = False, record_template: Optional[str] = "{text}", ) -> Union[Text, Record]: return super().build_with_record( sender=sender, sender_name=sender_name, input_value=input_value, session_id=session_id, return_record=return_record, record_template=record_template or "", )
Make sure that when you are using the ChatOutput
component, you provide the necessary parameters such as sender
, sender_name
, input_value
, session_id
, return_record
, and record_template
correctly. If any of these parameters are missing or incorrectly typed, it could lead to validation errors [1][2].
By ensuring the text
field is a valid string and correctly passing the parameters, you should be able to resolve the validation error.

Hi
The problem is not on the Chat Output component as it also fails if a drag the ChatInput component to a OpenAI Model
from langflow.
ChatGPT suggest the follwing:
`
from typing import Optional, Union
from langflow.base.io.chat import ChatComponent
from langflow.schema.message import Message
from langflow.field_typing import Text
from datetime import datetime
import logging
class ChatInput(ChatComponent):
display_name = "Chat Input"
description = "Get chat inputs from the Playground."
icon = "ChatInput"
def build_config(self):
build_config = super().build_config()
build_config["input_value"] = {
"input_types": [],
"display_name": "Text",
"multiline": True,
}
build_config["return_message"] = {
"display_name": "Return Record",
"advanced": True,
}
return build_config
def build(
self,
sender: Optional[str] = "User",
sender_name: Optional[str] = "User",
input_value: Optional[str] = None,
files: Optional[list[str]] = None,
session_id: Optional[str] = None,
return_message: Optional[bool] = True,
) -> Union[Message, Text]:
if input_value is None:
logging.error("input_value cannot be None")
raise ValueError("input_value cannot be None")
message = Message(
text=input_value,
sender=sender,
sender_name=sender_name,
timestamp=datetime.utcnow().isoformat(),
flow_id=None
)
logging.debug(f"Built message: {message}")
return message if return_message else input_value
`
It just seems strange that i need to make code adjustments to such a simple setup
from langflow.
I actually found a fix! If i add en "Text Output" in between there are not issue
from langflow.
I had same issue, after disabling return record value in chat input advanced option, issue not occurred.
