It was complaining:
Executing pythonRuntimeDepsCheck
Checking runtime dependencies for gnome_extensions_cli-0.10.1-py3-none-any.whl
- pydantic<3.0.0,>=2.3.0 not satisfied by version 1.10.14
The `gnome-extensions-cli` uses other packaged Python dependencies
and failing to build because the packaged versions of `more-itertools`
and `pydantic` are newer than what the project's dependency constraints
allow for.
Upgrading the package to the newest version fixes the build.
