Hi @centaur78 and @netchampfaris

I'm running into the exact same.

Environment:

• Debian 10
• Python 3.7

Here's the log:

Those files were not changed in this PR #11285.

I was able to migrate my site after my PR was merged. This issue is unrelated but I sent a fix.

#11552

[centaur78]

Thanks @netchampfaris

Just bench updated the PR #11552 , issue resolved.

[intrepidtechnology]

Thanks @netchampfaris, it's working perfectly now.

[kimsreng]

I still have the same issue with the development branch. What command can i use to fix it?
