Hi all, We encountoured an error with the galaxy api since the last galaxy-dist revision. here is an example of a command line that doesn't work (xxx stand for the admin key) : ./display.py xxxxxxxxxxxxxxxxxxxxxxxxxx http://localhost:18084/api/users we obtain the following error: HTTP Error 500: Internal Server Error As you can see, the request is done locally, without going through a proxy or apache. The galaxy log is the following: 127.0.0.1 - - [23/Apr/2013:19:55:26 +0200] "GET /api/users?key= xxxxxxxxxxxxxxxxxxxxx HTTP/1.1" 500 - "-" "Python-urllib/2.6" Error - <type 'exceptions.AssertionError'>: use_remote_user is set but no HTTP_REMOTE_USER variable Do you have an idea to solve this problem? Thank in advance for your answer. Best regards -- Fabien Mareuil | Centre d'Informatique pour la Biologie fabien.mareuil@pasteur.fr | Institut Pasteur 25,28 rue du Docteur Roux 75015 Paris, France
