AttributeError: 'NoneType' object has no attribute 'replace'

Hello. I’m happy with ERPNext which we use for production use on a local server.
Anyway we didn’t follow up with updates for a while. We were using version v7.
Recently we took a backup of SQL database. Unfortunately the machine where the ERP was running got stuck and we have no way to access to it.
I’m recently getting mad because we install Erpnext on a fresh new server on Amazon EC2, we then restored the backup we took on V7 and tried to follow and read everything about to not commit mistakes.
Unfortunately after bench migrate command we get this error.
We tried on different machines, I’ve read all the forum looking for help.
I’m not able to solve this.
Please, can you kindly help us?
Thank you

If you have installed latest version of ERPNext then you would have to upgrade using bench update first.

Hello. Thanks for reply.
I already tried to do bench update but it gives me same error at the end of operation.
For every attempt I do, I always get this error.
I was hoping to bypass this in some way.
I think the best would be some like “updated with error”, but I instead get that it’s not possible to access the frontend.
