Studio gets error after restoring from image "Studio's having trouble saving your work"

[Just Me]

I was using google cloud and I had to move from one project to another

So i create an image of my instalation and start a new NV

Everything is fine

Except that Studio gets this weir errors when I'm trying to update courses or create new courses

Studio's having trouble saving your work

The Studio servers encountered an error

or

Studio's having trouble saving your work

This may be happening because of an error with our server or your internet connection. Try refreshing the page or making sure you are online.

not sure how to check more details for this error

I found this
https://community.bitnami.com/t/studios-having-trouble-saving-your-work/48279

but since I'm not using bitnami... the path is different

@just me did you manage to solve this issue?

I am trying to export the demonstration course and I am getting this issue too. 

I have an ironwood installation on an EC2 Linux (ubuntu 16.04) instance. 

My log files (/edx/var/log/cms/edx.log) state the following:
