ebaysdk-python Authentication failed : Invalid Application

I am trying to connect ebay with python script. here is my code, I have used ebaysdk-python

import ebaysdk
from ebaysdk.finding import Connection as finding
from ebaysdk.exception import ConnectionError

try:

    api = finding(debug=True, config_file='myebay.yaml',)
    api_request = {
            'Keywords':'Harry Potter',
            'MaxEntries': 2,
            'AvailableItemsOnly':True,
    }

    response = api.execute('findItemsAdvanced', api_request)
    print response

except ConnectionError as e:
    print "\n\n\n",e
    print "\n\n\n",e.response.dict()

while running this I am getting below error. Here is the debug result

Any guess? what I am missing?

Thanks in advance.

You are calling with ebay api by production environment. you need to call with sandbox credential. your credential may be correct but you need to change the domain. ebaysdk-python api is by default calling to production environment.

change the line by passing ebay sandbox endpoint in domain.

api = finding(domain='svcs.sandbox.ebay.com', debug=True, config_file='myebay.yaml')

It will give you response Ack Success,

Hope this helps.
