help request: not seeing any data in the "Server log"

Howdy,
This tool looks great! I'm just trying it out for the first time - sorry for the noob questions. I'm struggling to get cloudwatch logs to feed into `Server Log`. I've tried setting the `--start-time` but no dice. I can list the lambda, invoke it from sls-dev-tools (and see the result in `Dashboard Logs`), and see stats - but the data is not feeding through.

How can I debug it?

## What I've tried

- fiddling with start time
- `sls-dev-tools -r eu-west-2 -n sls-dev-tools-test-prod -t '10 September 2020 00:00 GMT'`
- deploying to different regions (none working): eu-west-2, us-west-1, af-south-1
- confirmed that cloudwatch logs are present = check
```sh
CWLOG=/aws/lambda/sls-dev-tools-test-prod-hello && aws logs describe-log-streams --log-group-name $CWLOG | jq -r .logStreams[].logStreamName | tr '\n' '\0' | xargs -0 -n1 aws logs get-log-events --log-group-name $CWLOG --log-stream-name | jq -j ".events[].message"
# returns logs correctly
```
- multiple sls-dev-tools versions:
- tried latest 2: 1.1.10 & 1.1.8

## More info on my environment

context,
message: "hi world",
}),
};
callback(null, response);
