When I run:

xcode-build-server config -project XYZ.xcodeproj -scheme "XYZ Dev"

I get this error:

I installed xcode-build-server via Homebrew. I'm using Xcode 16 on macOS Sequoia.

Any idea how to fix it?

Did your buildServer.json is valid? did you modify it?

[wojciech-kulik]

Hmm, the scheme was different, so it looks like this command doesn't support updating scheme. When I deleted buildServer.json it worked

[SolaWing]

it support update, but the error shows your json file is corrupted

[wojciech-kulik]

Hmm, not sure why it would happen, the file seemed to be fine, I didn't do any manual changes. Nevertheless, the issue doesn't occur anymore, so I'm closing the ticket.
