executing commands in AWS ebextensions

问题

I receive the following error while trying to upload my instance in aws elasticbeanstalk:

The configuration file .ebextensions/setup.config in application version t5 contains invalid YAML or JSON. 
YAML exception: while scanning a quoted scalar in "<reader>", line 3, column 18: command: 
"aws s3 cp s3:elasticbeanstalk-u ... ^ found unexpected end of stream in "<reader>", 
line 5, column 1: ^ , JSON exception: Unexpected character (c) at position 0.. Update the configuration file.

Below is what is included in the setup.config file:

container_commands:
    01_setup_apache:
        command: "aws s3 cp s3:elasticbeanstalk-us-west-2-273610000489/enable_mod_rewrite.conf /etc/httpd/co

I am working with AWS elastic beanstalk and since I can't modify the httdp conf file to AllowOverride All in order to clean-up my URL with rewritte rule, I was suggested to work with ebextensions: http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/customize-containers.html

Update:

I think what runs problem is this:

RewriteEngine On

located in htaccess. almost like it cant accept rewritenegine being turned on.

Always check your .ebextensions before committing them into Elastic Beanstalk. A resource that I use to check my files http://www.yamllint.com/

If you are trying to modify Apache config then I would suggest using 'files' in ebextensions. read more...

I believe you're trying to achieve the following:

files:          
  "/etc/httpd/conf.d/enable_mod_rewrite.conf": 
     mode: "644"
     owner: root
     group: root
     content: |
       AllowOverride All

Based on George's answer, this worked for me. May help some other who ran into the same glitch:

files:
  "/etc/httpd/conf.d/enable_mod_rewrite.conf":
     mode: "644"
     owner: root
     group: root
     content: |
       <Directory /opt/python/current/app/>
       AllowOverride All
       </Directory>

This is using a django app, so you need to place the .htaccess file in the main project directory. If you place in the static folder only unauthorised users still can see/click some content after pressing cancel on the login popup.
