I am getting an error while trying to run a process segment using the Track and Trace module. Here is the code (with the segment name removed):

When I check the material lot 000000289, it lists its status as Complete and that it is Available as well.

Here is what the console shows when I get the Material lot and the core properties:

```auto
>>> 
MaterialLot (25667638-b8eb-40f4-ac70-d00574ca9eee, 0000000289, 0 parents, 0 children, 1 custom properties, 0 complex properties)
{UUID=25667638-b8eb-40f4-ac70-d00574ca9eee, Name=0000000289, Description=, Enabled=true, Creator=Unknown, ResponseSegmentUUID=121c336c-b241-4efb-abd9-3c343ec9f5f7, MaterialRef=Response Material Definition, ___Material Definition Name Removed___ , MaterialRefType=ResponseMaterialDef, MaterialRefUUID=486c95f8-a240-454c-ba75-238cbe71ad56, LotAssemblyType=null, LotStatus=Complete, LotLocationRef=Response Equipment, ___Equipment Name Removed___ , LotLocationRefType=ResponseEquipment, LotLocationRefUUID=003346e9-48c0-4f9e-84bc-841aa2904e6b, LotUnits=null, LotSequence=1, LotAvailabilityStatus=Used}
>>> 

```

Does anyone know how to resolve an error of this flavor?

```auto

I would just submit this to Sepasoft support, probably won’t get much traction here.
