[Migrated] The "zappa update <stage>" command disconnects API Gateway and Lambda function.

[jneves]

Originally from: Miserlou/Zappa#2207 by hidekuma

When creating events for scheduling in zappa_settings.json, the API Gateway and Lambda function are disconnected.
The "zappa unschedule " command also disconnects the two services, is there a solution?

Context

Python 3.7, with pyenv, virtualenv

"events": [{
    "function": "app.cron",
    "expression": "rate(1 minute)"
}],

then

zappa update <stage>

API Gateway and Lambda functions are disconnected.

Expected Behavior

The connection between API Gateway and Lambda is not interrupted, and the registered event bridges must be applied.

Actual Behavior

API Gateway and Lambda functions are disconnected.

Possible Fix

Steps to Reproduce

1. Add events to zappa_settings.json
2. zappa update stage
3. API Gateway and Lambda functions are disconnected.
