I created a project(v 2025.2), there I added some serverless functions.
Everything was fine untill yesterday. Now project isn’t uploading throwing some random errors like:
failed with the following error ---
[ERROR] There were errors building this component:
- An internal error occurred while building app function:

Or this:
--- hubspot-serverless-package-uid failed with the following error ---
[ERROR] There were errors building this component:
- Couldn’t build serverless package because there’s a problem in `package.json`. Run `npm install` under `app/functions/package.json` and try again. Details: `com.hubspot.chirp.core.ChirpRpcFailureInternalError: UNKNOWN#UNKNOWN[com.hubspot.serverless.rpc.error.ServerlessChirpError]: Serverless package creation failed due to an internal error with the serverless package creation service. Wait a bit and try again. See error details for more information: Lambda package creation failed due to an internal error with the lambda package creation service. See error details for more information: Api[name=lambda, httpMethod=POST, subPath=package] Failed to process your request.`.

Do I need to downgrade my project??

try it again. i was getting internal errors yesterday but it was due to AWS being down. It just went away later in the day.

Hi @Riyadh9292

There was a server-side issue with HubSpot yesterday, which is likely why the project wasn’t uploading properly.

Please try uploading the project again today, and if you still face the issue, let us know.

Also, rather than downgrading the project version, I would recommend upgrading it to version 2026.03. However, before making any changes, please try it again today first, as yesterday’s error may have been caused by the temporary server outage.

I hope this helps you out. Please mark it as Solution Accepted and Like to help another Community member.
