### Is there an existing issue for this?

- [X] I have searched the existing issues

### Current Behavior

When invoking a lambda with a nodejs runtime and local executor, localstack is unable to handle payloads containing a single quote.

### Expected Behavior

Locally executed nodejs lambdas should be able to handle any stringified json payload

### How are you starting LocalStack?

With a docker-compose file

### Steps To Reproduce

https://github.com/alxyuu/localstack-issue

### Environment

```markdown
- OS: MacOS 11.5.2
- LocalStack: latest (0.12.18)
```


### Anything else?

The culprit appears to be in how node gets executed locally, with a single quoted eval:

doing something like `event_json_string.replace("'", "'\\''")` may be a simple resolution to the issue.
