We have a private app which now fails being deployed to production.
I’ve done changes locally and ran “hs project upload” and it works fine in Sandbox. I were happy with the changes and ran “hs project upload --account=production”, it ran the build but never triggered the automatic deploy.
I’ve tried locally using “hs project deploy” and got this error back:
[ERROR] We encountered an issue deploying build 21. Please review the build details for more information, or reach out to HubSpot support if you need assistance.
- This deploy would remove the Abonnemang component. To proceed, run the deploy command with the `--force` flag
- This deploy would remove the Service Subscription component. To proceed, run the deploy command with the `--force` flag
Not sure why it think I want to remove components in production compared to Sandbox. I’m a bit concerned to run it with --force as it could cause these cards to stop working. The build itself looks the same as in sandbox and it has no errors.
We’re still on the 2023.2 platform.

Here’s our full build log. We’re aware that the version needs to be updated soon.
The log is the same in Sandbox, there’s no error logs.

Hey @fredrik-r
I’m pulling in some more experts to get more eyes on this. 
Hey @MichaelMa @Humashankar @HubSpot_Corey any thoughts on this when you get a chance? We’d appreciate your help.
Thanks, Victor
This has been resolved now.
I double checked the build and compared every file with the previous build.
Apparently the uid in the app.json got changed, not sure why or how.
But when I changed it back to how it was the deploy worked, not sure why I didnt get that error in sandbox.
