Langflow in Docker Container ID Not Found

[wesley-sappington]

Hey all!

I'm installing a (headless) Langflow in a docker container, which connects to another docker container with my Node app. This is coordinated with docker-compose.

I've created a Dockerfile as recommended here which copies the JSON file of my flow into the container. This copying works as expected.

I have made sure that my Node application is using the same Flow ID as what I've found in the Flow JSON file.

But when I try to query Langflow, I get this error:

langflow-1 | HTTPException: 404: Flow identifier langflow-1 | 7c4e63f3-9faf-4eb2-9e52-8aba09fba47b langflow-1 | not found

This means that my docker compose setup is successfully coordinating communication between my Node app and Langflow in their distinct containers, but for some reason, Langflow can't find the flow file.

I have verified the ID matches that which is found in the JSON and the JSON is located in app/flows

Any help would be immensely appreciated - thanks!

Hey @wesley-sappington! I'm here to help you with your Langflow Docker issue. Let's get this sorted out! 🤖

A similar issue was discussed in a closed thread, but no solution was found in the comments ^[1].

For your specific problem, here are a few things to check:

1. UUID Format: Ensure that the Flow ID is a valid UUID. Langflow expects the flow ID to be a valid UUID, and if it is not, it cannot find the flow ^[2].

2. Flow Association: Verify that the flow is correctly associated with the user or system making the request. The flow ID might not be associated with the user, which can lead to a "not found" error ^[2].

3. Flow Data: Check if the flow has data. Even if the flow ID is valid, the flow might not have any data, which can cause this error ^[2].

4. Directory Structure: Ensure that the directory structure inside the Docker container is set up correctly. The LANGFLOW_CONFIG_DIR environment variable and volume mapping should be configured properly. The directory where the JSON file is located should match the expected structure ^[3].

5. Environment Variables: Make sure that the necessary environment variables are set for Langflow to recognize and load the flow files. This can be done through the command line or a .env file ^[4].

Double-check these aspects to ensure that Langflow can access and recognize the flow file in your Docker setup.

Hi @wesley-sappington,

I am having also some problems with the Dokcer. Currently I am using the docker_example, but want to use custom components adding my own code. Do you know how could I do this?

Sorry I cannot help with this question right now
