hi zackliu,

I have tried all the possibilities but not working for me and working only with negotiate (http trigger). I assumed signalr trigger not invoked. Is there any configuration missed me for my end?

[zackliu]

If the trigger was totally not invoked (You can check it from Function's log), I assume the upstream settings in SignalR Service is not correct. And what's the browser console output when you try to send message? If there's no output, it seems to be the upstream setting is not set?
If you can't find out any reason, you can give me you ResourceID and time, I can check more from backend.

[Prabumca12]

There is no error in browser console and function log and find below SignalR Service settings. I'm assuming some settings from my end. Also, I'm not able to resourceID and time.

[zackliu]

I checked the configuration of your resource, and found the upstream setting was empty. Please check the document to add the upstream setting. https://docs.microsoft.com/en-us/azure/azure-signalr/concept-upstream
For a quick setting and sample, see https://github.com/aspnet/AzureSignalR-samples/tree/chenyl/bi-direction/samples/BidirectionChat#deploy-project-to-azure-function
In the Upstream URL Pattern, fill in the <function-url>/runtime/webhooks/signalr?code=<signalr_extension-key>

[Prabumca12]

Yeah you're correct. I missed that upstream setting. It's working fine. Is there any possibility to downgrade this project to .Net Core 2.2

[zackliu]

It should work in 2.2, while you need to downgrade function tool from v3 to v2
