Appsettings.json documentation

appsettings.json is a configuration file located in the server application’s root directory. Documentation of the file for Origam version earlier than 2025.11 is here. …

[jsusen (Jindřich Sušeň)]

FIX: Invalid uris in configuration did not result in a descriptive error message

[zcapkova (Zuzana Čapková)]

The application also fails to start unless AllowedCorsOrigins is filled in appsettings.json. When the parameter is missing or left empty, the application won’t start. It works when the application url is filled.

@zcapkova

The application also fails to start unless AllowedCorsOrigins is filled in appsettings.json

That is expected. I have added a check to make sure the error message is descriptive.

[zcapkova (Zuzana Čapková)]

Why is it mandatory to fill it if I am running an application that doesn’t have any cross-origin requests?

[jsusen (Jindřich Sušeň)]

I have checked again and it actually works with empty array but not with null. I will make sure that an empty array is sent if nothing is in the config.
