CLU Key is invalid! Works well in portal, but key fails when I use it in Bot.

Hi MS Team,

I have created a CLU model in language studio I have been using this application. It seems the key format has been changed and the key provided is longer in length compared to previously, as a result I am facing issue while running my bot application. The key works well in portal.

Hello manish chitre,

I understand that you're encountering an issue with the CLU key when integrating it into your bot application. While the key works in the portal, it fails in your bot,

Here are a few steps to troubleshoot the issue:

Ensure that you are using the correct key associated with your CLU model. Sometimes, there may be multiple keys, and using the wrong one can lead to authentication failures.

Since the key format has changed, verify its length and structure in your bot application to ensure it aligns with the expected format.

Ensure that your bot application is correctly configured to use the CLU service. This includes checking any environment variables or configuration files where the key might be stored.

Confirm that you are using the correct API version in your bot application that corresponds to the CLU service.

I Hope this helps. Do let me know if you have any further queries.Thank you!

Hello manish chitre,

Welcome to the Microsoft Q&A and thank you for posting your questions here.

This issue might be due to the recent change in the key format for Azure Language Studio, which has been causing similar problems for other users.

However, check your appsettings.json file to ensure the key is correctly entered without any discrepancies. If you are using environment variables, make sure they are correctly set and accessible by your application. Also, your Bot Framework and related packages should be up-to-date to handle the new key format. If the issue persists, contact Microsoft Priority Customer Support.

I hope this is helpful! Do not hesitate to let me know if you have any other questions or clarifications.

I checked it multiple times, but still there is no issue with my code at all. Please try to run a replicate it at your end. I have even worked in Microsoft Bot Framework support team previously so please try to replicate this asap, since it can be a problem to many users too, few users have already reported it earlier. https://learn.microsoft.com/en-us/answers/questions/2128800/unable-to-connect-clu-project-with-bot-framework-c

Hello @manish chitre ,

There is an ongoing issue while deploying the bot service through language studio portal, our internal team is looking for it.

As a workaround you need to manually configure the template and deploy it.

Here is the full steps provided in this Qna case.

So, try creating bot service using above steps and check if the same issue persists.

Let me know if you have any query.

Thank you
