Python3.6 environment JSON decode error

[paranoiks]

I'm trying to run a lambda function locally, with the docker image set to Python3.6 For some reason, I get a weird error, even when there are no imports in the code

This is the code of the lambda function:

`def lambda_handler(event, context):

return {
    'statusCode': 200,
    'body': 'asd'
}`

The command I'm running:

docker run --rm -v C:\sandbox-lambda:/var/task:ro,delegated lambci/lambda:python3.6 lambda_function.lambda_handler --network="host"

The error:

PS C:\sandbox-lambda>

You're passing --network="host" as the JSON event (which isn't valid JSON)

If you wanted to include that docker argument, you need to have it before you specify the image
