SignalR binding breaks Static Web App

I'm trying to experiment with Static Web App, I had a small app running fine locally, including using SignalR service for communication.

However, when I actually created the Static Web App, the functions wouldn't work : all I got was "function host is not running". I managed to track this down to the presence of a SignalR binding, for instance :
```json
{
"type": "signalRConnectionInfo",
"name": "connectionInfo",
"hubName": "my_hub",
"direction": "in"
}
```
Having or not the connection string in the settings, or using an `out` binding doesn't change anything.

I saw a suggestion to add App Insight, and indeed I got something, namely this exception, much more useful than just "functions host is not running", and seems to correlate :
```

Secret initialization from Blob storage failed due to missing both an Azure Storage connection string and a SAS connection uri. For Blob Storage, please provide at least one of these. If you intend to use files for secrets, add an App Setting key 'AzureWebJobsSecretStorageType' with value 'Files'.
