This is not a new package in my profile, I've been using it for a long time. Since both error seemed to be related to Guile, I removed all Guile-related packages from my profile and tried upgrading again. This time, the upgrade succeeded.

The reason your custom package failed is because it is using guile-2.2,
but the dependencies are built with Guile 3.0.

Changing the native-input to 'guile-3.0' should do the trick.  Otherwise
you can change the dependencies to 'guile2.2-json' and similar.

Thanks for testing!
