The go list -json -m command normally returns the following JSON inside the senet repo:

{
	"Path": "github.com/macabot/senet",
	"Main": true,
	"Dir": "/home/user/repos/github.com/macabot/senet",
	"GoMod": "/home/user/repos/github.com/macabot/senet/go.mod",
	"GoVersion": "1.23.0"
}

However, it returns multiple JSON objects when there is a go.work file in the macabot directory:

{
	"Path": "github.com/macabot/hypp",
	"Main": true,
	"Dir": "/home/user/repos/github.com/macabot/hypp",
	"GoMod": "/home/user/repos/github.com/macabot/hypp/go.mod",
	"GoVersion": "1.23.0"
}
{
	"Path": "github.com/macabot/senet",
	"Main": true,
	"Dir": "/home/user/repos/github.com/macabot/senet",
	"GoMod": "/home/user/repos/github.com/macabot/senet/go.mod",
	"GoVersion": "1.23.0"
}

This can't be parsed by json.Unmarshal, which gives the error:

invalid character '{' after top-level value
