Thank you for your message. I was able to getv.surf.idw working. I
posted the original question because I am struggling to use the
r.mblend add-on module. I have reached out and worked with the
r.mblend authors on Github but still haven't been able to solve my
issue. The error I am getting has to do with v.surf.idw:
So you're trying to blend two overlapping rasters of different
resolution? Can we see the output of r.info for both of the rasters?

The author said that "/The |v.surf.idw| module is failing because it
can not find the attribute table of one the vector layers. This
probably means something is going on with the GRASS bank-end
database./" and requested the following information:

As you can see, when I try to list the existing tables, nothing comes
up. After this issue, I started working with just v.surf.idwto see if it
The sqlite database is empty since you probably have no vector layers in
your mapset. That's not necessarily a problem.
might be an issue with the module itself, but that seems to be working
fine. Does anyone have any suggestions as to how to solve the
v.surf.idw issue that I'm having within the mblend module?
Thanks!
