I’m trying to set up this example https://github.com/HubSpot/ui-extensions-examples/tree/main/quote-generator
After hs project upload command I get an error
[ERROR] Failed to build serverless package due to validation errors in `/app/app.functions/serverless.json`. Address the validation errors and try building again.
Your HubSpot plan doesn't include serverless functions, so you can't use them to create app functions. Remove the `appFunctions` property from /app/app.functions/serverless.json. If you need access to serverless functions, talk to your admin about upgrading your plan.
How can I add serverless functions to my developer account? I want to check them before we start a real production project.
Hey, @AlekseyMalakhov 
Looking at the README for these examples, it states the following requirements:
- You must have an active HubSpot account with Sales or Service Hub Enterprise access.
- Your HubSpot account must be enrolled in CRM development tools public beta. You can enrol by visiting Product Updates > Betas.
- You must be using the latest HubSpot CLI.
I double-checked my dev test portal, and it doesn’t have the option to enroll in the required beta, but my production portal does.
You can also try opening an issue in the repo to confirm this info. But my read of the documentation doesn’t show the option you are after. It may be that this limitation will lift once the beta is complete, and I don’t have any details at this time.
Best,
Jaycee
