Hi @anchalanshrid  
We're glad you're here. When you get a chance, please [introduce yourself on this forum thread](https://forum.getodk.org/t/-/6671).

> Deployments using appcfg are no longer supported.

That means you won't be able to upload this particular version on Google Cloud (Aggregate v1.7.4).

Why did you choose an old version of Aggregate?  
Are you aware that we no longer work on ODK Aggregate and [ODK Central](https://docs.getodk.org/central-intro/) is our new, recommended server?
