# This is a Bug Report

Using multi-line values (with yaml >) in an IoT definition results in an 'unexpected token' error.

For bug reports:
* What went wrong?  The following yaml:
```
events:
      - iot:
          description: >
            My multi-
            line value.
          name: enrollPlayer
          sql: >
            SELECT * FROM 'path/#'
            WHERE prop = 'value'
```
complain of an "Unexpected token" when deployed.   Looking at the value of `iotTemplate` in file `serverless/lib/plugins/aws/deploy/compile/events/iot/index.js`, it seems the trailing linefeed is being preserved:
```
           "Description": "My multi- line value.
            ",
            "RuleDisabled": "false",
            "Sql": "SELECT * FROM 'path/#' WHERE prop = 'value'
            ",
```
* What did you expect should have happened?  The multi-line input should not break the ending quote on the next line.
* What was the config you used?
* What stacktrace or error message from your provider did you see?
