Hi everyone,I recently have installed a local instance of galaxy in my computer, everything worked fine until I changed the path for library_import_dir in the universe_wsgi.ini file, to upload files to data libraries.I followed the Galaxy documentation to setup this feature:This is the path in the universe_wsgi.ini filelibrary_import_dir = /media/New/Vladimir/My_RNA-seq/The steps I followed are: Admin > Data Library > Create new data library > Add datasets > Upload directory of files file format was set to auto-detect server Directory was /media/New/Vladimir/My_RNA-seq/ and we chose the option to link to files instead of copying themWhen I try to upload files, galaxy displays the following error:Error Traceback:⇝ AttributeError: 'NoneType' object has no attribute 'new_state'<?xml version="1.0" ?><traceback> <sysinfo> <language version="2.7.3">Python</language> </sysinfo> <stack> <frame> <module>weberror.evalexception.middleware</module> <filename>/home/labinmunologiaulpgc/galaxy-dist/eggs/WebError-0.8a-py2.7.egg/weberror/evalexception/middleware.py</filename> <line>364</line> <function>respond</function> <operation>app_iter = self.application(environ, detect_start_response)</operation> <operation_context> try: __traceback_supplement__ = errormiddleware.Supplement, self, environ app_iter = self.application(environ, detect_start_response) try: return_iter = list(app_iter)</operation_context> </frame> <frame> <module>paste.recursive</module> <filename>/home/labinmunologiaulpgc/galaxy-dist/eggs/Paste-1.7.5.1-py2.7.egg/paste/recursive.py</filename> <line>84</line> <function>__call__</function> <operation>return self.application(environ, start_response)</operation> <operation_context> environ['paste.recursive.script_name'] = my_script_name try: return self.application(environ, start_response) except ForwardRequestException, e: middleware = CheckForRecursionMiddleware(</operation_context> </frame> <frame> <module>paste.httpexceptions</module> <filename>/home/labinmunologiaulpgc/galaxy-dist/eggs/Paste-1.7.5.1-py2.7.egg/paste/httpexceptions.py</filename> <line>633</line> <function>__call__</function> <operation>return self.application(environ, start_response)</operation> <operation_context> []).append(HTTPException) try: return self.application(environ, start_response) except HTTPException, exc: return exc(environ, start_response)</operation_context> </frame> <frame> <module>galaxy.web.framework.base</module> <filename>/home/labinmunologiaulpgc/galaxy-dist/lib/galaxy/web/framework/base.py</filename> <line>132</line> <function>__call__</function> <operation>return self.handle_request( environ, start_response )</operation> <operation_context> self.trace( message="Starting request" ) try: return self.handle_request( environ, start_response ) finally: self.trace( message="Handle request finished" )</operation_context> </frame> <frame> <module>galaxy.web.framework.base</module> <filename>/home/labinmunologiaulpgc/galaxy-dist/lib/galaxy/web/framework/base.py</filename> <line>190</line> <function>handle_request</function> <operation>body = method( trans, **kwargs )</operation> <operation_context> kwargs.pop( '_', None ) try: body = method( trans, **kwargs ) except Exception, e: body = self.handle_controller_exception( e, trans, **kwargs )</operation_context> </frame> <frame> <module>galaxy.webapps.galaxy.controllers.library_common</module> <filename>/home/labinmunologiaulpgc/galaxy-dist/lib/galaxy/webapps/galaxy/controllers/library_common.py</filename> <line>927</line> <function>upload_library_dataset</function> <operation>**kwd )</operation> <operation_context> widgets=widgets, replace_dataset=replace_dataset, **kwd ) if created_outputs_dict: if cntrller == 'api':</operation_context> </frame> <frame> <module>galaxy.webapps.galaxy.controllers.library_common</module> <filename>/home/labinmunologiaulpgc/galaxy-dist/lib/galaxy/webapps/galaxy/controllers/library_common.py</filename> <line>1049</line> <function>upload_dataset</function> <operation>state = tool.new_state( trans )</operation> <operation_context> tool_id = 'upload1' tool = trans.app.toolbox.get_tool( tool_id ) state = tool.new_state( trans ) errors = tool.update_state( trans, tool.inputs_by_page[0], state.inputs, kwd ) tool_params = state.inputs</operation_context> </frame> </stack> <exception> <type>AttributeError</type> <value>'NoneType' object has no attribute 'new_state'</value> </exception></traceback> I have been looking for a solution to fix this problem on the web without success. thank you very much
