Hi there,

I’m currently facing several problems with the galaxy instance I’m managing. 
I’m going to send a mail per problem so sorry in advance : for flooding !

The first problem I’m facing is that we can’t download HTML datasets from 
Galaxy. Here is the error I got when I try to do download an HTML dataset :

URL: http://use.galaxeast.fr/datasets/ff16fe18e3db62e7/display?to_ext=html
 line 431 in respond
  app_iter = self.application(environ, detect_start_response)
 line 85 in __call__
  return self.application(environ, start_response)
 line 640 in __call__
  return self.application(environ, start_response)
File '/data2/galaxy/production/galaxy/lib/galaxy/web/framework/base.py', line 
131 in __call__
  return self.handle_request( environ, start_response )
File '/data2/galaxy/production/galaxy/lib/galaxy/web/framework/base.py', line 
190 in handle_request
  body = method( trans, **kwargs )
 line 245 in display
  return data.datatype.display_data(trans, data, preview, filename, to_ext, 
offset=offset, ck_size=ck_size, **kwd)
File '/data2/galaxy/production/galaxy/lib/galaxy/datatypes/data.py', line 353 
in display_data
  return self._archive_composite_dataset( trans, data, **kwd )
File '/data2/galaxy/production/galaxy/lib/galaxy/datatypes/data.py', line 235 
in _archive_composite_dataset
  params = util.Params( kwd )
File '/data2/galaxy/production/galaxy/lib/galaxy/util/__init__.py', line 683 in 
  self.__dict__[ key ] = sanitize_param( value )
File '/data2/galaxy/production/galaxy/lib/galaxy/util/__init__.py', line 488 in 
  raise Exception('Unknown parameter type (%s)' % ( type( value ) ))
Exception: Unknown parameter type (<type 'NoneType'>)

We don’t want to disable the sanitize process and we try to add some tools that 
generate HTML datasets into the whitelist but it didn’t solve our problem.

Version of Galaxy : release_16.04

Any idea about what the problem can be ?

Many thanks in advance for any help,

Best regards,
