Hi,

Is this happening on your first use of Frappe or was it working well and the error happened after some other event?

3

@smino It was working well but I tried some customization, then it is showing this error.

4

Try bench migrate or bench update and see if they complete.

have you got any solutions ?

10

Initially, I installed Ubuntu Desktop and restored the DB which caused this issue.
Then restored the DB on Ubuntu Server Live which resolved the issue and my DB was restored successfully.

I ran restore command and ‘bench update’ after the restore was completed.

11

did you install hrms module?

In my case, I have install erpnext v14 in my Development Setup {Ubuntu Docker} after that I run the restore command & see the restore successfully completed.

then I have run bench start command & I got the same error which you have already mention in your post.

12

i have the same problem any solutions

13

get export of all data like sales purchase stock and payments and delete all transactions of company and export data again

14

I am also getting the same,
how you resolved it.
I have tried “branch update” as said in this discussion.
could you please reply?
