Hi, I just installed and configured Galaxy to run on our SGE cluster. I tried to upload a file (fasta, ggff3, ...) without any success... it seems I missed something at the level of the config. the log shows the following message: galaxy.web.framework DEBUG 2010-05-06 17:17:06,940 Error: this request returned None from get_history(): http://machine/Galaxy/tool_runner/upload_async_create galaxy.web.framework DEBUG 2010-05-06 17:17:06,940 Error: this request returned None from get_history(): http://machine/Galaxy/tool_runner/upload_async_create galaxy.web.framework DEBUG 2010-05-06 17:17:06,940 Error: this request returned None from get_history(): http://machine/Galaxy/tool_runner/upload_async_create galaxy.web.framework DEBUG 2010-05-06 17:17:06,940 Error: this request returned None from get_history(): http://machine/Galaxy/tool_runner/upload_async_create any tip where to look at? I am making use of the proxy config too (http://bitbucket.org/galaxy/galaxy-central/wiki/Config/ApacheProxy)... which actually works very fine in our other instances that are running on local (not clustered). thanks, Erick
