Unable to write to commit message inputBox

Question

So I have the below code, which has been working fine for several months, but at some point it stopped working, and I simply can't figure out why it isn't working anymore.

I did some debugging and for some reason the repository is undefined.

import * as vscode from 'vscode';
import { Repository } from './git';

export function activate(context: vscode.ExtensionContext) {
    context.subscriptions.push(vscode.commands.registerCommand("my_extension.my_command",
        (repository: Repository) => {
            repository.inputBox.value = "commit message goes here";
        }));
}

Apparently if you have more than one repository open, my original code worked just fine, but if you only had one repository open, then repository was undefined and I had to use the GetRepo function to get the repository.

So my final code ended up looking like this:

import * as vscode from 'vscode';
import { Repository } from './git';

export function activate(context: vscode.ExtensionContext) {
    context.subscriptions.push(vscode.commands.registerCommand("my_extension.my_command",
        (repository: Repository) => {
            repository = GetRepo(repository);

            repository.inputBox.value = "commit message goes here";
        }, { repository: true }));
}

function GetRepo(repository: Repository | undefined): Repository {
    if (repository === undefined) {
        let gitExtension = vscode.extensions.getExtension<GitExtension>('vscode.git').exports;
        let api = gitExtension.getAPI(1);
        repository = api.repositories[0];
    }

    return repository;
}
