Invalid JWT token format

[cnieblaog]

Hi Geoffrey,

Thanks for sharing your code.

As of May, Google no longer allows sending emails with a username and password, so I'm trying your program to send Gmail emails with OAuth2.

When requesting authentication, after accepting authorization in the browser, I receive the error: "Invalid JWT token format."

Reviewing the code, the error is generated in TEmailOAuthDataModule.IdHTTPServer1CommandGet() in the following statement:
var jwt := TJWT.Create(FOAuth2_Enhanced.IDToken);

Before executing this statement, the value of FOAuth2_Enhanced.IDToken is an empty string ('').

I'm not familiar with the authentication process, but I assume the IDToken should contain data.

Do you know what could be happening?

Regards

It works for me... but google sometimes updates security options and my test app keeps the old settings. Here is something you can try.
Go to
https://console.cloud.google.com/auth/scopes

Make sure you have the correct app selected. and click on the "Add or remove scopes". add "openid" , and save the changes. See if that fixes things
