Error in Step 3 [Error]: Contour: failed to read smoothed input!

When running a Sequoia data set in Pix4Dmapper v 4.4.12, the processing fails on Step 3 with the error in the title of this post. The selected outputs are NDVI map and point-shapefile (not polygon). Any advice is appreciated.

 

The full error log is:

Processing: Substep Ortho index indices finished.

Processing: Index statistics

Processing: Export range index

[Error]: Contour: failed to read smoothed input!

[Error]: Export range index failed!

[Error]: >>>Export range index<<< failed with error (failed to run a  step!)!

[Error]: >>>Export range index<<< failed with error (failed to run a  step!)!

Hi Jacob, Can you check what is the grid size? Also have you checked contour lines as an output?
