Error Running Dockerrun.aws.json file ERROR: Value

Question

I'm trying to run the current dockerrun.aws.json file with eb local run but it gives back this error.

ERROR: ValueError :: Extra data: line 2 column 1 - line 8 column 1 (char 61 - 478)

It gives the error after these debug messages.

The rest of the code is located here: https://github.com/bchav/beanstalk-docker-signup. I was attempting to follow the tutorial here on the topic, https://www.youtube.com/watch?v=vaZmVSlWwyA

I've tried just about everything from getting rid of spaces in the dockerrun file to minifying it. I'm not sure what the error could be?

Attached is image of error

-- UPDATE --

So I asked another question here (Upgrade Python on Mac from 2.7 to 3.6 (or newest) for elastic beanstalk client AWS) and got my Python upgraded to the newest 3.6, it was able to give me a more detailed error, but still an error. Attached is newest image of error.
