I receive the error below when trying to run a GRASS command from the processing toolbox:

2016-09-20T12:07:28 2 Uncaught error while executing algorithm

TypeError: environment can only contain string

I found a previous issue in the tracker with the same problem, but it was closed as it was unable to be reproduced.

I have found that it is due to the OpenLayers Plugin being installed. Uninstalling the plugin resolves the issue.

Apologies, but I can't help more than that.

  • Status changed from Open to Feedback

#3 Updated by Michel ZEVORT over 7 years ago


I have this problem when the OpenLayers Plugin is actived.
I work with Qgis 2.16.3, 64 bits under Windows7.

This problem is also discribed in #15412.

#4 Updated by Giovanni Manghi over 7 years ago

  • Resolution set to not reproducable
  • Status changed from Feedback to Closed

Closing for lack of feedback. Reopen if necessary.

Note: the OpenLayes plugin seems to cause problems in Processing as reported and confirmed by some (but not others), but the error is different from the one reported here.
