"Problem with passing variables from chat input."

[ahomonicky]

Hello,
I would like to ask for some advice.
I am a new user of Langflow and I am building a bot for a company knowledge base.
The server is running on Ubuntu, and I wrote a Flask API to receive messages from Slack.
It took me some time to figure it out, but now I am successfully sending sender_name and session_id into Langflow (please see the attached screenshot of the JSON output from the log and the variables in the chat input).
These variables are mapped in the Prompt under sender_name, and session_id is also correctly stored in the Message Store.
Unfortunately, for some reason, the chat input variables are not passed further down the flow.
I am also attaching a screenshot of the flow itself.
It is probably just a small mistake, but I can't find it.
Could I kindly ask for your advice? Thank you very much!

Prompt variable

"But unfortunately, the variable is not passed into the prompt at all."

CURL log test

Somewhere along the flow, the value of sender_name gets replaced with "AI", as can be seen from the log.
But I have absolutely no idea where this happens, and I don't know how to fix it.
When I tried adding a Text Input component before the Chat Input to test it, it even printed {question} multiple times instead of {sender_name}.
I'm attaching the test flow again.

Prompt settings

Output from prompt

I have been working on this for several days now and still haven't figured it out.
Hopefully someone knows what might be causing it.
Thank you very much in advance for any help.
The Langflow version I am using is 1.3.4 (latest).

Thanks a lot

Aleš

Hello @ahomonicky! I'm Dosu, your friendly bot here to help you solve bugs, answer questions, and guide you as a contributor. I'm ready to assist you while you wait for a human maintainer. Let's tackle this together!

To ensure that the sender_name variable is correctly passed through the flow in Langflow without being replaced by "AI", you should explicitly set the sender_name in the inputs when running the component. Here's an example of how you can do this:

outputs = await run_single_component(
    ChatInput, inputs={"sender": "User", "sender_name": "Aleš Homonický"}, run_input="Test"
)

Make sure that the sender_name field is set to be visible and not required in the configuration, so it can be overridden without defaulting to "AI" ^[1]. Additionally, check the configuration of your nodes to ensure that the sender_name is correctly mapped in the Prompt node and that there are no default values set to "AI" in the node settings ^[2].

If the issue persists, verify that the connections between nodes are correctly established and that the sender_name variable is being passed through each node without being altered. You might also want to check if there are any conditions or logic in your flow that might inadvertently reset or change the sender_name variable to "AI".
