MAX Upload file size

[sweco-nlmdek]

Hi, i have langflow running on a azure kubernetes.
When testing i came across the following error when uploaden a 2.5mb large PDF file : 413 (Request Entity Too Large)

So i have been trying to solve this, but no matter what i tried i aint working.

frontend is of type: LoadBalancer

i have added the following env variables, both in frontend and backend.

• name: MAX_CONTENT_LENGTH
  value: "100000000" # 100MB
• name: MAX_UPLOAD_SIZE
  value: "100M"
• name : LANGFLOW_MAX_FILE_SIZE_UPLOAD
  value: "100"

i have tried specifying like this in the frontend:
nginx:
client_max_body_size: "200M"

To solve this issue using the Helm chart, add this on the ingress.yaml file

...
  rules:
    - host: myhost.local
      http:
        paths:
          - backend:
              service:
                name: langflow-service
                port:
                  number: 8080
            path: /
            pathType: Prefix
          - backend:
              service:
                name: langflow-service-backend
                port:
                  number: 7860
            path: /api
            pathType: Prefix
...

This will override the frontend call to request directly to the langflow-service-backend

https://github.com/langflow-ai/langflow/blob/main/docker/frontend/nginx.conf this is the nginx config file that causes the issue.

A fix for this is merged now in the main repo (langflow-ai/langflow#7664). However, setting the env variable LANGFLOW_MAX_FILE_SIZE_UPLOAD in the frontend container does not yet take effect since the template does not set it yet. I will create a MR for this in this repo once the next version has been released
