Missing Mandatory Parameter Exception

Every time i try to login to a restricted page i get this error:

Symfony\Component\Routing\Exception\MissingMandatoryParametersException: Some mandatory parameters are missing ("node") to generate a URL for route "entity.node.canonical". in Drupal\Core\Routing\UrlGenerator->doGenerate() (line 172 of C:\inetpub\venus\core\lib\Drupal\Core\Routing\UrlGenerator.php).

if i refresh the page then it redirects fine the second time but this error keeps coming up upon first attempt to redirect.

Any help would be greatly appreciated this module is essential for one of my websites.

thanks.
