I have a MacMini M2 machine running Sequoia 15.1 OS. On this machine, I am running a Virtual Machine, utilizing the Virtualization.Framework, with the same OS version, 15.1.
Logging into my account in the System Settings is successful. Next, I need to add my account in Xcode 16.1. While the initial login is successful, Xcode immediately displays the following error:
Decoding Error.
There was a failure decoding response: (HTTP 401, 60 bytes) The data couldn’t be read because it isn’t in the correct format.
As a result, I cannot see any account information, teams, etc.
A very similar bug has been reported at this issue - https://developer.apple.com/forums/thread/759877, but there has been no progress or updates there.
Is there any chance to fix this and get it working?
While the initial login is successful, Xcode immediately displays the following error: Decoding Error.
Yes. I’ve seen exactly the same behaviour. I discussed this with various folks here at Apple and it seems that Virtualization and Xcode are doing the right thing here, but we need to fix something on the Developer website (well, its back-end infrastructure).
I filed my own bug about this and it was closed as a dup of the main bug we’re using to track this (r. 131573827). I don’t have any info to share as to when that’ll be fixed. But, like you, I’m hoping for sooner rather than later.
Share and Enjoy
