Failed to do graphite POST request error #130

Closed gregvolk closed 8 years ago

First of all, thank you for publishing Graph Explorer, it looks pretty neat.

I have a working Graphite system (I can generate & view graphs via the default interface) but when I attempt to view graphs in Graph Explorer I get... Error: Failed to do graphite POST request to http://nlpanms-1:8085/render: error:.

I read the GE documentation and added the three Header set Access-Control lines to httpd.conf and restarted without errors. I have also gone through the config.py and local settings files and don't see any issues there either. When using the Firefox browser call debugger, I do see the following error in the Network Response tab: SyntaxError: JSON.parse: unexpected end of data at line 1 column 1 of the JSON data.

Any suggestions for additional troubleshooting? I have included the render request & response below.

I figured this out. I was still referencing the development (builtin) graphite server by port and not the apache server on a different port. Duh!
