No space left when running CD/CI pipelines on serverless

Hello, in my company we’re considering to acquiring Robot Units to run pipelines as we find it very useful. But we’re encountering an issue when running Build.and.publish package.
These are our logs:

Process (string): Build.and.publish

Afterward, we tried with another github repository and this time we got a more detailed exception message:

No space left on device : '/tmp/home/.nuget/packages/uipath/24.10.94.62718/bessvdqq.jiq'

The used machine is the Serverless machine (we’re using service trial robot units) created by default when setting up pipeline’s runtime:

How can we deal with this “No space left” error? Where is our mistake?
Aren’t Serverless machines supossed to get resources on demand? Why does it say that we’ve no more space instead of spend more robot units?

Thanks in advance
