Hi, I received an error when I was trying to view the details of existing workflows through API. I can see 4 workflows owned by myself successfully. But viewing the details of any workflow got me a 500 error. ./display.py <my_key> http://galaxy.nbic.nl/galaxy/api/workflows Collection Members ------------------ #1: /galaxy/api/workflows/e037fdb493429c2a name: test id: e037fdb493429c2a #2: /galaxy/api/workflows/13120e62d0fbb985 name: imported: Partial Workflow for Student Project (1) id: 13120e62d0fbb985 #3: /galaxy/api/workflows/c9468fdb6dc5c5f1 name: GAPSS SNP calling id: c9468fdb6dc5c5f1 #4: /galaxy/api/workflows/3f5830403180d620 name: GAPPS CAGE id: 3f5830403180d620 4 element(s) in collection ./display.py <my_key> http://galaxy.nbic.nl/galaxy/api/workflows/e037fdb493429c2a HTTP Error 500: Internal Server Error 500 Internal Server Error The server has either erred or is incapable of performing the requested operation.
