I'm build a project using SignalR. As Front I'm using .Net Core, as Back I'm using React. So in my localhost the project is working, but when i deploy this project i get an error. In azure I have created: 2 web application - one used for cliend, and the other one for server. 1 Azure SignalR service (i tested it online and it worked) 1 Azure SQL Database
So when i try to invoke Method it now working and show me this error. Someone know how to solve this problem?
So the problem was that my Database was empty... the migration did not upload, Update the database solved it.
