Hi everyone!

I’m encountering an issue with my developer account (super admin) when trying to create a Personal Access Key or a new project for UI Extension development.

  1. Personal Access Key Error:

    • When attempting to generate a key, I see the message:
      “Join the UI extensions developer beta and start building apps using Projects.”
    • Clicking the link leads to: “Product update no longer exists.”
    • Result: Complete blocker.

  2. New Project Creation Error:

    • The same message prevents project creation, halting UI Extension development.

Current Workaround:
If I create a test developer account (under my developer account), I can generate Personal Access Keys and build apps there. However, I need to use my developer account for publishing purposes.

Questions:

  • Has anyone else faced this issue?
  • Is this a permissions, configuration, or beta-access problem?
  • Are there any official solutions or workarounds?

Any guidance would be greatly appreciated!

Hi @IFuentes3 ,
This looks like an issue on HubSpot’s side, not something you can fix with permissions or settings.

HubSpot recently changed how UI Extensions and developer betas work. The message saying “Product update no longer exists” means the old beta link is outdated, or the feature is being reworked, or temporarily paused.

You can check this changelog post for more context: https://developers.hubspot.com/changelog/april-2025-rollup

You’re already doing the main workaround by creating and testing in a sub-developer account. If you need to publish from your main developer account, here’s what I’d suggest:

  • Reach out to HubSpot Support (or Partner Support if available) and ask them to enable access to UI Extensions and project tools on your main dev account. Be sure to mention the broken beta link and reference this issue.
  • Submit a ticket via HubSpot Developer Support, and the Developer Relations (DevRel) team can usually escalate access issues like this.
  • Keep an eye on updates and monitor the UI Extensions docs and the developer changelog for any updates or fixes.
  • Also, if your main developer account is tied to an older app, there might be some access restrictions compared to newer accounts, worth checking with support.

At this point, the best option is to wait for an official fix or get support to manually unlock access.

Hope this helps!

Thanks for the reply and help! I had to check the box for Gradual Releases in Account Defaults → Feature Releases to gain access to beta feature, which didn’t happen with another developer account I’d tried, but that should have been resolved.
