build-from-local Error: POST payload is too large (limit 9MB)

[radimkvet]

When using the build-from-local command to create a build on the platform from the local sources, if the source code is bigger than 9MB the command ends with an error message.

Repro steps:

1. Go into any repo with Actor source code bigger than 9MB
2. Follow the steps to build from local source
3. The command fails with the following message:

[ERROR]: The POST payload is too large (limit: 9437184 bytes, actual length: <your_size> bytes).

Zip build in KV seems to be the way to go https://apify.slack.com/archives/C0BQUEDQD1S/p1789738432725299?thread_ts=1789732928.127489&cid=C0BQUEDQD1S
