Error in QGIS 2.12-Lyon Windows 64bit

Tried to download cassava harvested area.

I have tested your use case and it works on Mac, so I am trying to figure out whether this is a Windows-related problem. Moreover, the error is located in a piece of code that should be removed. I will then update the plugin to version 0.2. In the meanwhile, you can try to open (with textpad, or similar) the file:

C:/Users/mbacou/.qgis2/python/plugins\geobricks_qgis_plugin_faostat\geobricks_faostat_connector.py

and remove the line 121:

print countries

After that you should restart QGIS and check whether the problem is still there.

I commented Line 121, but other problems remain. Looks like a Windows issue.

Version 0.2 is available from the plugin repository, could you please try to update your plugin?

[mbacou]

Just upgraded to v0.2, but still same messages:

Can you try to run the following code in the QGIS Python console? This works on Mac, I am trying to find out whether this is a Windows-related problem or not.

    response = urllib2.urlopen(req)
    json_data = response.read()

It seems that the communication with the DB is interrupted before all the required data is transferred. I have updated slightly the code, could you please try the following one? If this works I'll make version 0.3 😄

Ha no sorry I added [truncated] because the response was too long for Github! The response was a complete json.

[Kalimaha]

Ah ok! Well, if the code works in the Python console it should work in the plugin as well, considering it is the same code! I will release version 0.3 anyways, it may solve your problem.
