UI Extensions Install Issue

ACurtis001 — Mon, 09 Jun 2025 23:36:01 GMT

Hi all, first post here.

Need: Prepping for a demo of (2) UI Extensions in my Developer Portal. Planned on using Custom CRM Card and Sidebar Action Button.I confirmed the following in my Dev portal about being in the (Private) beta:Build App Cards Powered by UI Extensions with CRM Dev Tools
Public Beta - Everyone is taking part in beta

However, here is what I am seeing in Terminal:Failed to upload mapbox-api project files to alex-dev [dev account] (242983888)
[ERROR] Couldn't create a React extension with your file `/app/ui-extensions-examples/display-iframe-modal/src/app/extensions/iframe-modal-example-card.json` because your portal (`242983888`) doesn't have access to this beta. Make sure you are uploading to the correct standard hubspot account.

ISSUE:
I need access in my existing Dev Portal to these two (2) UI extensions I created today using the HS CLI (Custom CRM Card/Sidebar Action Button).See below text of Terminal responses, along with Hubspot web pages with details around this beta access issue.[SUCCESS] New project UI Extension Use Case successfully created in alex-dev [dev account] (242983888).

Per Terminal:

Failed to upload UI Extension Use Case project files to alex-dev [dev account] (242983888)
[ERROR] Couldn't create a React extension with your file `/app/extensions/example-card.json` because your portal (`242983888`) doesn't have access to this beta.

Any help/guidance appreciated.

Hi! When you're in your developer portal, have you created a test account to set up your private app and generate an access token? The UI extensions are built locally using the developer project framework and powered by a private app which you create in a test account. I would verify that when you are in your IDE and are at the 'hs auth' point the correct Hub ID for the test portal is where you're opted in and set up.

Many thanks for the reply.
I just created a test account.
Does attached look correct in order to setup Custom CRM Card and Sidebar Action Button? look correct?

Yes, that's the one. Participation in the beta allows you to create cards, sidebar action button, other components.
