How to add AzureSignalRConnectionString in Cloud

Question

Hello,

I used the following quickstart tutorial to implement a first Azure Function + SignalR Service.
(https://learn.microsoft.com/en-us/azure/azure-signalr/signalr-quickstart-azure-functions-python)

My preferred language is python. After the tutorial i tried to push the code to cloud.

Locally the code works (=> "AzureSignalRConnectionString" in local.settings.json),
but in the cloud each request fails. With the error:
"The SignalR Service connection string must be set either via an 'AzureSignalRConnectionString' app setting, via an 'AzureSignalRConnectionString' environment variable, or directly in code via SignalROptions.ConnectionString or SignalRAttribute.ConnectionStringSetting."

I cleary understand, that i have to add the AzureSignalRConnectionString from the local.settings.json. But i have no idea where!?!

In my Azure Function App i added a new Application setting. I named it "AzureSignalRConnection" an pasted the Connection String from the local.settings.json file. But it still doesn´t work.

Is there something else to add than just this application setting (For example add a reference to this new application setting)? Or where is the correct place to add the Connection-String?

Or principal... what is the correct way to go?

With best regards Patrick

Hi @Patrick Schneider

You need to define the key as "AzureSignalRConnectionString" instead of "AzureSignalRConnection" if you are defining it in the application settings.
As per the article it defines the AzureSignalRConnectionString in local.settings.json. This setting (inside local.setting.json) is only for your local environment. Once you deploy your function you need to copy every setting in local.settings.json to the application settings of your function app.

Hope the above helps you to resolve the issue. Please let me know if you need any assistance.
