Hi All,

I faced a problem after I tested the Bio-Blend API. I cannot access the
history anymore with the below error messages. Although, I tried
installation from the scratch, but I got the same error message. Please let
me know how to fix this problem. Thanks!

(GALAXY User Interface)


  "xhr": {

    "readyState": 4,

    "responseText": "{\"err_msg\": \"Uncaught exception in exposed API
method:\", \"err_code\": 0}",

    "responseJSON": {

      "err_msg": "Uncaught exception in exposed API method:",

      "err_code": 0


    "status": 500,

    "statusText": "Internal Server Error",

    "responseHeaders": {

      "Date": "Wed, 03 Dec 2014 15:50:02 GMT\r",

      "cache-control": "max-age=0,no-cache,no-store\r",

      "Server": "PasteWSGIServer/0.5 Python/2.7.8\r",

      "Connection": "close\r",

      "content-type": "application/json\r"



I found the error message in the Galaxy instance shell interface.
