Hi all, I get the following error when I try to export a specific history to file: 10.1.5.190 - - [07/May/2012:18:01:08 +0200] "GET /history/export_archive HTTP/1.1" 500 - "http://galaxy.immunbio.mpg.de/" "Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.2.24) Gecko/20111108 Fedora/3.6.24-1.fc14 Firefox/3.6.24" Error - <type 'exceptions.TypeError'>: <galaxy.tools.parameters.basic.UnvalidatedValue object at 0x8ba67d0> is not JSON serializable URL: http://galaxy.immunbio.mpg.de/history/export_archive File '/galaxy/galaxy_server/eggs/Paste-1.6-py2.7.egg/paste/exceptions/errormiddleware.py', line 143 in __call__ app_iter = self.application(environ, start_response) File '/galaxy/galaxy_server/eggs/Paste-1.6-py2.7.egg/paste/recursive.py', line 80 in __call__ return self.application(environ, start_response) File '/galaxy/galaxy_server/eggs/Paste-1.6-py2.7.egg/paste/httpexceptions.py', line 632 in __call__ return self.application(environ, start_response) File '/galaxy/galaxy_server/lib/galaxy/web/framework/base.py', line 160 in __call__ body = method( trans, **kwargs ) File '/galaxy/galaxy_server/lib/galaxy/web/controllers/history.py', line 678 in export_archive history_exp_tool.execute( trans, incoming = params, set_output_hid = True ) File '/galaxy/galaxy_server/lib/galaxy/tools/__init__.py', line 1517 in execute return self.tool_action.execute( self, trans, incoming=incoming, set_output_hid=set_output_hid, history=history, **kwargs ) File '/galaxy/galaxy_server/lib/galaxy/tools/actions/history_imp_exp.py', line 106 in execute include_deleted=incoming[ 'include_deleted' ] ) File '/galaxy/galaxy_server/lib/galaxy/tools/imp_exp/__init__.py', line 428 in setup_job jobs_attrs_out.write( to_json_string( jobs_attrs, cls=HistoryDatasetAssociationEncoder ) ) File '/galaxy/galaxy_server/eggs/simplejson-2.1.1-py2.7-linux-x86_64-ucs2.egg/simplejson/__init__.py', line 268 in dumps File '/galaxy/galaxy_server/eggs/simplejson-2.1.1-py2.7-linux-x86_64-ucs2.egg/simplejson/encoder.py', line 214 in encode File '/galaxy/galaxy_server/eggs/simplejson-2.1.1-py2.7-linux-x86_64-ucs2.egg/simplejson/encoder.py', line 282 in iterencode File '/galaxy/galaxy_server/lib/galaxy/tools/imp_exp/__init__.py', line 327 in default return simplejson.JSONEncoder.default( self, obj ) File '/galaxy/galaxy_server/eggs/simplejson-2.1.1-py2.7-linux-x86_64-ucs2.egg/simplejson/encoder.py', line 190 in default TypeError: <galaxy.tools.parameters.basic.UnvalidatedValue object at 0x8ba67d0> is not JSON serializable I tracked the problem down to a single bed file. I copied it into a new empty history and I can still not export this history to a file. This file doesn't have any special characters in either its name, info or annotation. I can't find anything special about this file... Any help is greatly appreciated! Best regards, Sarah
