I'm trying to import workflows from a 16.07 instance to a 17.01 one. The tools are slightly different, so I'm getting a lovely Internal Server Error which tells me nothing. So I go to the log and find more detail that is almost, but not entirely, completely unhelpful: - - [24/May/2017:12:13:47 -0500] "POST /workflow/import_workflow HTTP/1.0" 500 - "" "Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36"

Now, if I could see the argument values in the traceback instead of just the argument names, it should give me a strong idea about which part of the workflow is causing the problem. Apparently the inspect or cgitb modules in python will accomplish this, but I have no idea where to insert it so that it will take effect for the whole of Galaxy.

After a few false starts, I found that editing some code in lib/galaxy/web/framework/middleware/ achieved my desired effect. It is quite verbose because the workflow dictionary is huge, but it actually allowed me to pinpoint the problematic tool: Query to Tabular.

Here is the original error, cgitb style:

Will the workflow load if the latest version of the tool is installed first?

You may be doing that already, but just checking.

There have been some changes in the way dependencies are handled during tool installs in Galaxy version 17.01 and further improved in version 17.05 (the most current release). Upgrading the Galaxy instance would also be a good idea and might be enough to handle this case (load the workflow successfully, then edit it to resolve tool mismatches between the two Galaxy servers), but that would need to be tested.

I posted as an answer intentionally. :) My main concern was with being able to more quickly clean information about exceptions from the Galaxy log (now and in the future). Although I should have posted the code change I made!

To fix this problem, I tried to manually update the JSON syntax of the old workflow (which used Query Tabular 0.1.3 while new instance has 3.0.0). I made a new workflow with 3.0.0 and copied parameters manually. Then I downloaded the new workflows' JSON and copied the tool_state part over to the old workflow. No dice, still got the input_opts KeyError when importing. So I tried importing the new workflow and I got the same error, i.e. I couldn't import the workflow I had just exported a minute earlier. So this has to be a Galaxy bug. I can't try this on main because it doesn't have Query Tabular installed. I'm running a Jetstream instance and 17.05 isn't an option yet. This is on 17.01.

Np :) I wanted to make sure we got this settled out as a usage versus code problem (that needs to be fixed) before this dropped off as answered.

I'll recruit some developer help for more troubleshooting. Thanks for the follow up! Jen
