Bonjour, Je fais plusieurs upload par jour depuis plusieurs semaines maintenant, sans aucun problèmes. Et à l'instant, j'ai une erreur qui reviens constamment, impossible de faire d'upload. Est-ce que quelqu'un sait quelque chose sur cette erreur? Merci beaucoup! Voici l'erreur : Error Traceback: View as: Interactive <http://127.0.0.1:8080/library_common/upload_library_dataset#> | Text <http://127.0.0.1:8080/library_common/upload_library_dataset#> | XML <http://127.0.0.1:8080/library_common/upload_library_dataset#> (full) <http://127.0.0.1:8080/library_common/upload_library_dataset#> ⇝ AttributeError: 'NoneType' object has no attribute 'new_state' URL: http://127.0.0.1:8080/library_common/upload_library_dataset Module weberror.evalexception.middleware:*364* in respond <http://127.0.0.1:8080/library_common/upload_library_dataset#> view <http://127.0.0.1:8080/library_common/upload_library_dataset#> >> <http://127.0.0.1:8080/library_common/upload_library_dataset#> app_iter *=* self*.*application*(*environ*,* detect_start_response*)* Module paste.recursive:*84* in __call__ <http://127.0.0.1:8080/library_common/upload_library_dataset#> view <http://127.0.0.1:8080/library_common/upload_library_dataset#> >> <http://127.0.0.1:8080/library_common/upload_library_dataset#> *return* self*.*application*(*environ*,* start_response*)* Module paste.httpexceptions:*633* in __call__ <http://127.0.0.1:8080/library_common/upload_library_dataset#> view <http://127.0.0.1:8080/library_common/upload_library_dataset#> >> <http://127.0.0.1:8080/library_common/upload_library_dataset#> *return* self*.*application*(*environ*,* start_response*)* Module galaxy.web.framework.base:*132* in __call__ <http://127.0.0.1:8080/library_common/upload_library_dataset#> view <http://127.0.0.1:8080/library_common/upload_library_dataset#> >> <http://127.0.0.1:8080/library_common/upload_library_dataset#> *return* self*.*handle_request*(* environ*,* start_response *)* Module galaxy.web.framework.base:*190* in handle_request <http://127.0.0.1:8080/library_common/upload_library_dataset#> view <http://127.0.0.1:8080/library_common/upload_library_dataset#> >> <http://127.0.0.1:8080/library_common/upload_library_dataset#>body *=* method*(* trans*,* ****kwargs *)* Module galaxy.webapps.galaxy.controllers.library_common:*927* in upload_library_dataset <http://127.0.0.1:8080/library_common/upload_library_dataset#> view <http://127.0.0.1:8080/library_common/upload_library_dataset#> >> <http://127.0.0.1:8080/library_common/upload_library_dataset#>****kwd *)* Module galaxy.webapps.galaxy.controllers.library_common:*1049* in upload_dataset <http://127.0.0.1:8080/library_common/upload_library_dataset#> view <http://127.0.0.1:8080/library_common/upload_library_dataset#> >> <http://127.0.0.1:8080/library_common/upload_library_dataset#>state *=* tool*.*new_state*(* trans *)* *AttributeError: 'NoneType' object has no attribute 'new_state'*
