  • 1.  MSAL VBO Authentication Issues

    Posted 02-09-2023 19:01

    I have been trying to use the MSAL (2.1.0) VBO to authenticate with a registered app to access the Graph API. I am unable to perform any action as they all result in the same error message:

    Internal : Could not execute code stage because exception thrown by code stage: One or more errors occurred.

    I am unable to dig any deeper due to the generic message it returns. I have not modified the VBO in any way and have made sure these prerequisites are installed:

    1. Collection Manipulation
    2. File Management
    3. Windows Compressed File
    4. Microsoft.Identity.Client.dll that was provided by the MSAL download has been placed in C:\Program Files\Blue Prism Limited\Blue Prism Automate\

    I am at a loss as to where to look next as there doesn't seem to be any discussion around this yet. I have even installed this VBO in a fresh installation of Blue Prism 6.9 just to make sure there aren't existing conflictions in our DEV area. What am I missing?

    Hi @Tim Argenbright

    This is due to an AggregateException being thrown. You should be able to capture it by adding an additional catch like this:

    catch (AggregateException err) {
  Exception = err.ToString();
}

    Just add the above code snippet immediately after the close curly brace of the MsalServiceException catch block.

    Cheers,

    Hi @Eric Wilson,
    I'm facing MSAL Authentication issue with the below error. I imported the MSAL.NET v2.2 version with the dll. I have performed the prerequisites as mentioned in the Guide. Can you help me to resolve the issue.

    Hello @Amrutha Sivarajan,

    We're going to need more information.

    • What version of Blue Prism are you using?
    • Which action on the MSAL VBO are you calling?
    • Can you post a screenshot of the action properties (make sure to obscure any sensitive data)?
    • I assume you've set the Tenant ID and other properties?

    Cheers,

    Thank you @Eric Wilson for the swift response.

    Below are details you have asked for:
    1. We are using BP7.0 and have configured the Azure as mentioned in the User Guide.

    2.  At the stage for Authentication, when it calls the 'Get Auth Token - Client Secret' action, it takes a while to execute and returns the above error message.

    3. Screenshots below:
