We have a microservice project set up with blazor server front end project. We are trying to send notificatio on status change using signalR. We have created a hub inheriting from AbpHub and followed Microsofot's documentation to connect to hub from blazor server project. We are getting "Antiforgery token validation failed. The required antiforgery cookie ".AspNetCore.Antiforgery.RfvzpqGUp6I" is not present." when hubConnection.StartAsync() is invoked.
Do we have to add any configuration to make this work?
Hi, It is a microservice template project with blazor server front end. We just created a hub in blazor server project and implemented hub connection from a razor page using "Microsoft.AspNetCore.SignalR.Client" package. Please find the signalR hub connection code below. "await hubConnection.StartAsync();" would invoke the signalR negotiate endpoint POST https://localhost:44314/signalr-hubs/applicationstatuschangenotification/negotiate?negotiateVersion=1 - 0
Hi, I have already tried passing the RequestVerificationToken and the cookies to signalR connection. But it is giving the same error. ".AspNetCore.Antiforgery.RfvzpqGUp6I" is not present." This cookie ".AspNetCore.Antiforgery.RfvzpqGUp6I" doesn't exist in the browser cookies. Instead there is a similar cookie with name ".AspNetCore.Antiforgery.dHbfFikoQ1Y".
Hi,
Cookies and request header are getting passed. We are using blazor server hosting model and not web assembly. We only have ".AspNetCore.Antiforgery.dHbfFikoQ1Y" cookie in the browser which is set from auth server. Not sure why it is trying to validate antiforgery token ".AspNetCore.Antiforgery.RfvzpqGUp6I" from blazor server.
Hi, The issue was due to the incorrect signalR url. The url didn't have the hub name in kebab-case. It started working after url changed to "/signalr-hubs/application-status-change-notification".
But now getting issue with authorization. The token is getting passed in Authorization header, but signalR negotiation gives the following error.
Hi,
I'm getting the token in the Authorization header. But I'm still getting unauthorized.
We have integrated elsa workflow to abp project. It was all working fine with abp v7.0.3. But when we updated abp to version 7.1 following issues started happening
- Unable to access elsa dashboard api's as automapper mappings configured in elsa package stopped working.
- Elsa workflow instances doesn't save properly when updated, as entity change tracking doesn't work. Elsa gets the entity from the database and maps the latest changes to the entity using automapper and then saves the dbcontext. But the entity is in detached state after mapping and hence changes not saved.
Can you please shed some light on what changed with the version 7.1 that might be causing this issue. Elsa is also using .net 7 and automapper version 12.0.0.

Hi, we have added the automapping for elsa dashboard manually. And the dashboard issue is sorted. But major issue we are facing is with workflow instance not getting updated. Following is the code in elsa to save the instance. On debugging we found that entity is in detached state and hence change tracking not working for update.

That fixed the issue. Thank you.
