Please help us solve this. system is broken
Same!
I am facing same Issue
Panic Level: High 
How i can go back previous version for example to v12.0.8 ??
You have to go to the erpnext folder (And then the frappe folder) and execute:
git checkout v12.0.8
@Nahuel_Nso
I do that then execute bench migrate i git version 12.0.8 then execute bench restart
I git this when trying login to the system
Try bench migrate again. If it does not work, edit your /sites/SITE_NAME/site_config.json and set maintenance_mode (or something like that) to 0
Go to config folder (cd config) then open common_site_config.json and change value of “maintenance mode”:1 to 0 and save. then do bench restart
common_site_config.json
{
“auto_update”: false,
“background_workers”: 1,
“maintenance mode”:0

@Nahuel_Nso, @Azhar_Islam
am facing a new problem after login to system all list view is empty and I can’t add new records
like this
Try bench build
Thanks I am grateful for your help and fast response
Hi,
I get the same error on upgrading. Additional info: I have one site for testing with almost no data in there and, there the error is not shown. Also git checkout v.12.0.8 does work ( cd apps/frappe first ;-))
Kind regards,
David
Due to time difference, I doubt that there will be a solution to this problem today. I have just restored a previous backup and continuing to work on version 12.0.8.
Fixed with the latest release!
