CLI deployment fails without error message

**Describe the bug**

A clear and concise description of what the bug is.

I have static web content in `web` folder and a TypeScript function api in `api` folder.

If I set `swa-cli.config.json` to

```json
{
"$schema": "https://aka.ms/azure/static-web-apps-cli/schema",
"configurations": {
"link-shortener-demo": {
"appLocation": "web"
}
}
}
```

and then run `swa deploy --verbose silly` (with the deployment token set in environment variable) then the deployment succeeds (I see the updated time in the Azure portal) and I get the following output:

```

```

If I add the api to the `swa-cli.config.json`:

```json
{
"$schema": "https://aka.ms/azure/static-web-apps-cli/schema",
"configurations": {
"link-shortener-demo": {
"appLocation": "web",
"apiLocation": "api",
"outputLocation": ".",
"apiBuildCommand": "npm run build --if-present"
}
}
}
```

and re-run the `swa deploy --verbose silly` step then I see the following output:

```

Note that there is no output indicating that the content has been uploaded (and the site has _not_ been updated).

**To Reproduce**
Steps to reproduce the behavior:
see description above

Source repo: https://github.com/stuartleeks/link-shortener-demo

**Expected behavior**
I expect the `swa deploy` command to complete successfully with the api configuration included, and for the update to show in the Azure Portal.
