Impossible to access an attribute ("flashbag") on a null variable in FpOpenIdBundle::layout.html.twig at line 16

[tkuldeep]

Hi, I am seeing a exception in using this bundle.

• I did basic setup by reading https://github.com/formapro/FpOpenIdBundle/blob/master/Resources/doc/basic_setup.md.
• Then I visited url /login_openid and saw following exception.

Impossible to access an attribute ("flashbag") on a null variable in FpOpenIdBundle::layout.html.twig at line 16
500 Internal Server Error - Twig_Error_Runtime

• I am using symfony 2.7, "lightopenid/lightopenid":"dev-master" and "fp/openid-bundle": "dev-master"

Please help me here what should I do here.

has the session been started?

[tkuldeep]

@makasim No session was not started.

[makasim]

flashbag stores data into the session and if it is not started, the session object is not set to request. That's why you see this error.

Solution:

1. Start session
2. Overwrite the template and remove flashbag part.

@makasim Thanks a lot. But I think when user will get login, then session should automatically start for that user. So I am not getting what is logic behind starting it manually and also how to do that.
