SSO is the "name" of custom oauth provider.

@keisni can you reproduce it in demo site: https://demo.casdoor.com/ ? What is your application setting? Can you post the full JSON of the application?

[keisni]

@hsluoyz may I ask you that how can i export JSON of my application and provider?

[hsluoyz]

@keisni get the response of the API request (via Chrome F12)

[keisni]

this is the big icon option i talked about.
Im afraid that I cant upload the full app json coz it contains censtive information. basiclly it`s just a simple app with custom oauth provider.

@keisni it can't be reproduced in: https://door.casdoor.com/login/oauth/authorize?client_id=0ba528121ea87b3eb54d&response_type=code&redirect_uri=https%3A%2F%2Fforum.casbin.com%2Fcallback&scope=read&state=app-casbin-oa

(please ignore the final error like below)

[keisni]

@halozhy can you show me a example app with provider { "type": "Custom", "category": "OAuth" } showed with big icon?
