Oauth Prompt sign in is returning validation code sometimes and token sometimes

Palak Agarwal 20

I have a Bot framework project. We are using Oauth prompt sign-in card for authentication uwith aws cognito , but the bot is returning a validation code instead of token. It used to work fine before , is there a new bug introduced?

Hi Palak - Thanks for raising the query. The issue of receiving a validation code instead of a token after OAuth sign-in in your Bot Framework project may be due to problems in the authentication flow, specifically in the token exchange process or token response handling.

Possible Causes:

Token Exchange Process: The OAuth Prompt might not be correctly exchanging the validation code for an access token.

Token Response Handling: There might be issues in how the token response is processed after the user signs in.

Solution Steps:

Check Token Exchange Process:

Ensure the OAuth Prompt settings are configured to exchange the validation code for an access token.

Verify the OAuthPrompt handles the token response correctly.

Handle Token Response:

Update your code to correctly handle and use the token response after sign-in.

Validate Access Token:

Implement server-side validation to ensure the received access token is valid and issued by the intended authority.

Check for Errors:

Add error handling to catch and respond to issues during the token exchange process.

Code Snippet for Handling Token Response:

async loginStep(stepContext) { const tokenResponse = stepContext.result; if (!tokenResponse || !tokenResponse.token) { await stepContext.context.sendActivity('Login was not successful. Please try again.'); } else { const token = tokenResponse.token; // Use the token for further authentication or API calls. } return await stepContext.endDialog(); }

Additional Resources:

Bot Framework OAuth Prompt Documentation

By ensuring the token exchange and response handling are correctly implemented, you should resolve the issue of receiving a validation code instead of a token after sign-in.
