The commands parameter must be an array of commands, otherwise you'll receive such error. E.g:

import boto3
commands = [' echo "hello world"']
ssm_client = boto3.client('ssm')

output = ssm_client.send_command(
InstanceIds=["i-your_instance_id"]],
DocumentName='AWS-RunShellScript',
Parameters={
    'commands': commands
    }
)
