ExtractMultiValuesToPoints Fails in standalone script

I'm running AGP 2.8.0 with the default python environment. 

I can execute the same script fine through the toolbox, but if I schedule it for a later time, or run it in the IDE it fails with the error below. 

Error Info:
ERROR 160326: The table already exists.
Failed to execute (ExtractMultiValuesToPoints).

When I look this error up, under the Solution it says "There is no documented solution at this time."

I have env.overwriteOutput=True, but I also go through and check for the field names that are generated and delete them before I get to this step in the script.

Are you able to share your script? I think that's the only way forward.

I'm running the same script from the toolbox and scheduling it to run. It just fails on the scheduled attempts. I initially thought that it was something with paths not being fully written out, but I don't think that's the case. 

A few things:

  • I don't use concurrent licensing, so checking in/out the spatial license should have no effect
  • The NetCDF files are from the tkdegrib program produced by the National Weather Service. I download the data before running the script. 
  • The point file is just points, not multipoint. Definition query is set to just the US and then to nothing.

Hello. Thank you so much for your post about Extract Multivalues to Point. I am a Product Engineer on the Spatial Analyst team. We'd like to reproduce this issue and then try to solve it. Is it possible for us to get a copy of the data you used in this process?
