Pathfinding layer generation error #62

Closed aliaksei135 closed 3 years ago

aliaksei135 commented 3 years ago

When adding a path layer on top of a risk layer, generation results in a following error:

Traceback (most recent call last):
  File "seedpod_ground_risk\core\plot_server.py", line 213, in compose_overlay_plot
  File "<__array_function__ internals>", line 5, in flipud
  File "numpy\lib\twodim_base.py", line 148, in flipud
ValueError: Input must be >= 1-d.
Input must be >= 1-d.

Looks like this isn't anything to do with layer itself, but the plot server not being able to handle it.

I've been tracking this down and it appears that the issue comes from line 213 in plot_server.py. raster_grid appears not to be producing anything in some situations.

The usual cause for that is an OSM query failing and it returning a null. I'll close this as a duplicate of #61 in that case and we can reopen if it keeps occurring after #61 is fixed.
