Hello @Li_Jia for docker you can change the environment variable to unrestrict the file max size. have in mind this is not in relation to separate workflows sizes. this error is for this one workflow’s file that is exceeding the limit. if you wish to reduce the file size instead then please share the canvas so I can replicate and review on my side.

version: ‘3.8’
services:
n8n:
image: n8nio/n8n
environment:

  • N8N_DEFAULT_BINARY_DATA_MODE=filesystem
  • N8N_MAX_PAYLOAD_SIZE=1GB
  • EXECUTIONS_DATA_SAVE_MANUAL_EXECUTIONS=true
    volumes:
  • n8n_data:/home/node/.n8n

Thank you for your reply. I reinstalled my n8n and added two environment variables, hoping it will work. N8N_PAYLOAD_SIZE_MAX: 512
EXECUTIONS_DATA_PRUNE: “true”

Let me know how that goes!
N8N_PAYLOAD_SIZE_MAX: 512 ← this needs to be bigger then 512 - try 1GB

Currently It does work. May be run failed in the future after creating a lot workflow.
