Hello everybody, We're in the process of testing version 18.05 before updating our production server. The update process went fine but now I'm getting a "curious" error: Every time I make a dataset list of bam files the interfaces gives me following error when I try to run any tool: "Uncaught exception in exposed API method:" The error message in the galaxy.log is the following (here I just wanted to run hisat2, but it doesn't really matter which tool I try): 172.22.24.119 - - [19/Oct/2018:13:21:05 +0200] "POST /api/tools/toolshed.g2.bx.psu.edu/repos/iuc/hisat2/hisat2/2.0.5.2/build HTTP/1.1" 500 - "http://galaxy-test.inet.dkfz-heidelberg.de/?tool_id=toolshed.g2.bx. psu.edu%2Frepos%2Fiuc%2Fhisat2%2Fhisat2%2F2.0.5.2&version=2.0.5.2&__identifer=froqct2i1h" "Mozilla/5.0 (X11;
