Bench Update Error - New Issue

I have installed frappe and erpnext manually on fresh server.
It was working fine. Sales Funnel was throwing this error: Sales Funnel Issue · Issue #7546 · frappe/erpnext · GitHub

Now I am trying to do bench update so I am getting error. Even when i try bench setup nginx (as i added new site to test, so wanted to setup port for new site)

Any Idea or anyone can suggest something?

@fkardame,

did you make any changes in site_config.json?
please validate your site_config.json file content on jsonlint.com.

Thanks,

No Changes were made to any json file.
the jsonlint says valid json
Edited:
Well for 1 site i have added dropbox secret and access key and its uploading the backup successfully.

But now it looks like there i more issue in the site from user interface

Seems like you have merge conflicts in your .json files

@fkardame,

can you share the site_config.json & site_config.json file content ?

Thanks,
Makarand
