Need Assistance with 'command 'bob-code.generateDiffUsingLlm' not found' Error

  • 1.  Need Assistance with 'command 'bob-code.generateDiffUsingLlm' not found' Error

    Posted Wed March 25, 2026 10:20 AM

    Hello IBM Community,

    I'm currently encountering an issue where I'm unable to generate code from literate text. The error message is:
    'Failed to generate code from literate text. Please try again. Error: command 'bob-code.generateDiffUsingLlm' not found'

    Does anyone know how to resolve this issue? Any guidance or suggestions would be greatly appreciated.

    Thank you in advance for your help!

    Hi Vishnu,

    Can you please confirm what version of Bob you are using? I haven't seen anyone else encounter this issue so I can only suggest basic troubleshooting steps like restarting / reinstalling / updating Bob.

    Kind regards,

    Libby

    Hi Lizzy,

               I work with Vishnu and am encountering the same issue as well. As a FYI....I am not new to Bob and have developed several POCs/Projects with the earlier trial version. Having issues since I installed the new Bob. I tried reinstalling a few times to no avail. Any help is appreciated.

    I believe you have already tried all these options as per Bob:  if not ... can you?

    Solutions:

    1. Check installed extensions - Open VS Code Extensions (Cmd+Shift+X on Mac) and search for "Bob" or related extensions
    2. Reload VS Code - Use Command Palette (Cmd+Shift+P) → "Developer: Reload Window"
    3. Reinstall the extension - Uninstall and reinstall the extension that provides this command
    4. Check extension logs - View → Output → Select the extension from dropdown to see error messages
    5. Update VS Code - Ensure you're running the latest version

    Magesh,

    Maria has asked you to follow reset.  If that does not work.  I am sending you steps to follow (This is as per Bob since I could not recreate the same issue locally).  Please elt us know how it goes...

    *****

    The error 'command 'bob-code.generateDiffUsingLlm' not found' occurs specifically when using Bob's Literate Coding feature. This is a known issue with the literate coding functionality.

    Advanced Troubleshooting Steps:

    1. Check VS Code Developer Console (Critical):

      • Help → Toggle Developer Tools → Console tab
      • Look for additional error messages that might reveal the root cause
      • Check for extension activation failures or missing dependencies
    2. Verify Extension Activation:

      • Open Command Palette (Cmd+Shift+P / Ctrl+Shift+P)
      • Type "Developer: Show Running Extensions"
      • Verify Bob extension is listed and running without errors
    3. Clear Extension Cache:

      # Mac
      rm -rf ~/Library/Application\ Support/Code/User/workspaceStorage/*
      rm -rf ~/.vscode/extensions/ibm.bob-*
      
      # Windows
      rmdir /s "%APPDATA%\Code\User\workspaceStorage"
      rmdir /s "%USERPROFILE%\.vscode\extensions\ibm.bob-*"
      

      Then reinstall Bob extension

    4. Check VS Code Settings:

      • Open Settings (Cmd+, / Ctrl+,)
      • Search for "bob"
      • Verify no conflicting settings are disabled
    5. Try Alternative Approach:

      • Instead of literate coding, use Bob's chat interface
      • Describe what code you want to generate
      • Bob can still help without the literate coding feature
    6. Downgrade Extension (if recent update caused issue):

      • Right-click Bob extension → "Install Another Version"
      • Try previous stable version
    7. Contact IBM Support:

      • Visit https://bob.ibm.com
      • Report the specific error with literate coding
      • Include VS Code version, OS, and Bob extension version

    Workaround: Use Bob's chat interface or code actions instead of literate coding until this is resolved.

    *****

    Regards,

    Naren

    Hi Narendra,

            Thanks for your response. What exactly do you mean by a "Bob Extension"? I see this step in a lot of AI generated fixes to this issue and want to make sure I am not missing something here.  Bob is not an VSC IDE extension in the traditional sense of the word but an Agentic AI tool based on VSCode. Other than that yes, we have tried everything to no avail. Thanks again.

    Magesh,

    Thank you for your message... I believe you have already reported this issue through the link in the settings screen.  If not please do so.  Meanwhile did you try and use the Chat window in code node to add "your specific task" in the file  you are referencing to make the change at specific line number reference or so?  Did that workaround not work too?

    Regards,

    Naren

    Hey Naren,

             The chat window is dysfunctional at this point. We do not see anything there. The error mentioned above happens when we actually go to a specific line and request a change. We are currently in the process of evaluating multiple Agentic AI tools and would appreciate some escalation at this point. Thanks.

    Good morning , Up on checking real issue is the fact that once IBM BOB is installed , we are not getting the Sign in Page to connect to IBMi Account .

    On first launch, Bob will prompt you to sign in:

    1. Follow the authentication flow with your browser to login with your IBMid.
    2. Return to Bob after authentication is complete.

    Above steps are not happening or no pop ups .

    Hope this helps

    Hello Magesh,

    Just checking in, have you had a chance to try the steps in the documentation for resetting Bob to address the persistent issues? (https://bob.ibm.com/docs/ide/troubleshooting/ts-reset-application)

    I understood you're already experienced with Bob, but I didn't see a reset mentioned in the thread. I just want to make sure we've covered all the bases before escalating this to our expert team for a deeper investigation.

    Hi Maria,

           A reset/retry is the fist step we tried and it did not work for us. I am continuing to use the old installation that I had backed up until this version is stabilized. Please escalate to the next level if possible. Thanks!!
