NodeBB can't upload image from my laptop but not from AWS server

[Ken John]

I installed NodeBB both in my laptop and AWS server. In fact it runs perfectly in my AWS server but it's so wield that I can't upload image in my laptop (I use my laptop as a local development server with wifi network manager wpa_supplicant).

Both my laptop and AWS server run Ubuntu 18.04 server version with the same NodeBB v1.13.4-4, mongo v4.0, NGINX v1.14.0, node v12.17.0, NPM v6.4. Not superuser installation for NodeBB and Git Clone.

AWS Server: basic ufw setup, allow all incoming traffic as well as outgoing traffic.
My Laptop: No firewall ufw, default iptables, able to use express-fileupload in my laptop (and what package does NodeBB use to manage file uploading so that I can use it to build my Plugin?)

The only difference from my point of view is that my laptop operates in LAN and AWS server operates in WAN.

The Error I got from browser:

1. No preview.
2. Uploading 100%.
3. ×Error invalid-files
4. Failed to load resource: the server responded with a status of 500 (Internal Server Error) Http://192.168.0.121/api/post/upload

{"path":"/post/upload","title":"[[global:404.title]]"}

5. /nodebb log:

Hope someone know this issue. I'm kind of noob in Linux Server network configuration.
Thanks!

That's not quite the full error in the log you have there. Could you provide a little more context?

Have you checked that any upload-related settings are set up the same on both nodebbs?

What size of file are you uploading?

@Ken-John said in NodeBB can't upload image from my laptop but not from AWS server:

node v12.17.0,

Are you sure you are on node 12? Uploads are broken on node 14 right now.

@baris

You are RIGHT!!!
This problem really came from node version I installed in my laptop. To make "npm link" without sudo I was using nvm to install NodeJS and I forgot to select version 12.17.0.

Great teams. Thanks a lot!
