Deploy without build or api fails with "An unknown exception has occurred"

**Describe the bug**
Deploying a pre-built React-based app fails with "An unknown exception has occurred". The last console message written is "Using 'staticwebapp.config.json' file for configuration information, 'routes.json' will be ignored." Normally the next message is "No Api directory specified. Azure Functions will not be created." This problem only happens when running on MS-hosted ADO agents (ubuntu-latest), I can't get it to happen when running locally.

**To Reproduce**
Steps to reproduce the behavior:

Build a React app (in our case, using Create React App, running npm run build). Include staticwebapp.config.json. Ours just has typical React routing info. Then attempt to deploy as follows:

```
$token = az staticwebapp secrets list --name "$(azureResourceNames.StaticWebApp)" --query "properties.apiKey" | ConvertFrom-Json
swa deploy --app-location "$(System.DefaultWorkingDirectory)/app" --deployment-token "$token" --env Production --verbose silly
```

Here are the resulting logs:
