`chalice invoke` command does not work with CDK

I have a small lambda decorated with `@app.lambda_function()`, I can trigger it with `aws lambda invoke`, but not 'chalice invoke. Using the chalice command in the runtime folder I get `Error: could not find a lambda function named main_task.`

```
@app.lambda_function()
def main_task(event, context=None):
sync_data()
```

cdk --version
2.37.1 (build f15dee0)

chalice --version
chalice 1.27.1, python 3.7.12, darwin 21.6.0

Start by reproducing `chalice invoke` from the runtime folder with a CDK-deployed Lambda decorated with `@app.lambda_function()`. Trace how the command discovers the function named `main_task` and compare that with the function available through `aws lambda invoke`. Done means the command successfully invokes the CDK Lambda or clearly reports the unsupported integration.
