AttributeError: 'str' object has no attribute 'get' when HTTP 5xx

[Patataman]

When the server responses with a 520 and 524 (afaik, maybe with other 5xx errors also happens)

twitter-python-ads-sdk/twitter_ads/error.py

Lines 13 to 16 in a3dd581

	if response.body and 'errors' in response.body:
	self._details = kwargs.get('details', response.body.get('errors'))
	else:
	self._details = None

These lines return the error from the title because response.body is not a dictionary. A possible solution would be

if response.body and 'errors' in response.body:
    if type(response.body) is dict:
        self._details = kwargs.get('details', response.body.get('errors'))
    else:
        self._details = kwargs.get('details', [response.body])
else:
    self._details = None

But I don't know if response.body contains something useful to return as "details". As it is a server side error, I have no way to reproduce it
