Erro ao tentar adicionar Paytm Oauth usando o plugin discourse-oauth2-basic

SSO
1

Olá pessoal,

Estou tentando adicionar o Paytm OAuth ao meu fórum Discourse usando o plugin discourse-oauth2-basic, mas estou tendo problemas para fazê-lo funcionar. Segui as instruções no arquivo readme do plugin, mas quando tento fazer login com o Paytm, recebo uma mensagem de erro dizendo “Autorização expirou ou você trocou de navegador. Por favor, tente novamente.”
Não tenho certeza por que não está funcionando.

Qualquer ajuda seria muito apreciada!

Abaixo está o erro que encontrei no log do Discourse:

Erro:

Experimento o mesmo erro usando GitLab.com como provedor oauth com o plugin discourse-oauth2-basic (versão 0.3).

A autenticação no gitlab.com é bem-sucedida, então volto para o discourse com o URI de Redirecionamento correto:
http://example.com/auth/oauth2_basic/callback?code=…\u0026state=…

O erro é

Alguma atualização sobre isso, por favor me avise. Eu também estou enfrentando o mesmo problema
