MultiValueDictKeyError: "u'store_id'"

[vkaracic]

Hello! I'm trying to enable the DDT but it doesn't get displayed. If I go to __debug__/render_panel/ I get this exception (so I'm thinking this might be the key to my problem):

Traceback (most recent call last):
  File "/edx/app/ecommerce/venvs/ecommerce/local/lib/python2.7/site-packages/django/core/handlers/base.py", line 132, in get_response

    raise MultiValueDictKeyError(repr(key))
MultiValueDictKeyError: "u'store_id'"

Does anyone know how to fix this?

Did you use explicit setup to enable DDT on your project?

/ __debug__/render_panel/ by itself doesn't render anything, it needs some query string parameters, so this is unrelated to the issue you're seeing.

Sorry guys, we went on from this and I can't remember the details. I'm closing this issues and if it comes up again I'll reopen with some more details.

Got this error all of a sudden. Not sure what triggered it, but noticed the javascript was now requesting: "GET /__debug__/render_panel/?%5Bobject+Object%5D= HTTP/1.1" 500

Replicated by opening a console in Safari and Chrome and typing:
new URLSearchParams({"a":1}).toString();
which returns: "%5Bobject+Object%5D="

Was able to patch in toolbar.js with:

var url = djDebug.getAttribute('data-render-panel-url');
var url_params = new URLSearchParams();
url_params.append('store_id', store_id);
url_params.append('panel_id', this.className);
url += '?' + url_params.toString();

Yeah, this might be a good idea. @xi care to comment?
