I have problem with google drive credentials in AWS Lambda after I deploy my .zip file before calling the function on the local machine, all is work, but after I deploy zip in AWS after ~30min I having lambda function error

  "errorMessage": "[Errno 30] Read-only file system: 'drive-python-quickstart.json'",

"errorType": "OSError",

  "stackTrace": [

    [

      "/var/task/lambda_function.py",

      33,

      "lambda_handler",

      "pageSize=10,fields=\"nextPageToken, files(id, name)\").execute()"

    ],

    [

      "/var/task/oauth2client/_helpers.py",

      133,

      "positional_wrapper",

      "return wrapped(*args, **kwargs)"

    ],

    [

      "/var/task/googleapiclient/http.py",

      835,

      "execute",

      "method=str(self.method), body=self.body, headers=self.headers)"

    ],

    [

      "/var/task/googleapiclient/http.py",

      162,

      "_retry_request",

      "resp, content = http.request(uri, method, *args, **kwargs)"

    ],

    [

      "/var/task/oauth2client/transport.py",

      186,

      "new_request",

      "credentials._refresh(orig_request_method)"

    ],

    [

      "/var/task/oauth2client/client.py",

      761,

      "_refresh",

      "self._do_refresh_request(http)"

    ],

    [

      "/var/task/oauth2client/client.py",

      802,

      "_do_refresh_request",

      "self.store.locked_put(self)"

    ],

    [

      "/var/task/oauth2client/file.py",

      79,

      "locked_put",

      "f = open(self._filename, 'w')"

    ]

  ]

}

in file file.py I have this code :

 def locked_put(self, credentials):

    """Write Credentials to file.

    Args:

        credentials: Credentials, the credentials to store.

    Raises:

        IOError if the file is a symbolic link.

    """

    self._create_file_if_needed()

    _helpers.validate_file(self._filename)

    f = open(self._filename, 'w')

    f.write(credentials.to_json())

    f.close()

def locked_delete(self):

    """Delete Credentials file.

    Args:

        credentials: Credentials, the credentials to store.

    """

    os.unlink(self._filename)

I try to set f = open(self._filename, 'w') set to 'r', but it doesn't help, maybe whom know how can I fix it?

You are trying to write a file in a different directory but Lambda only supports /tmp directory for storing temporary files.
