When you use SAS^® Event Stream Processing Studio, you might encounter the following error when it deals with a model from SAS Model Manager.

This issue is caused by the corresponding champion model in a model repository that does not have its ASTORE code copied to a preconfigured directory. Typically, that directory  is at  /opt/sas/viya/config/data/modelsvr/astore.

You can examine this champion model by following these steps:

1. Open the model.


2. Click the Files tab.


3. Open the AstoreMetadata.json file, which contains code similar to the following:
   [
     {
       "name": "_1LA3UXOR00CO31HZUKMS9RF673",
       "caslib": "ModelStore",
       "uri":
   "/dataTables/dataSources/cas~fs~cas-shared-default~fs~ModelStore/tables/_1LA3UXO
   R00CO31HZUKMS9RF673",
       "key": "FE93CC8BD5CEA0FBD1C2D4763785B9FC403DBB83"
     }
   ]

   Instead, it should code that looks similar to this:

   [
     {
       "name": "_1LA3UXOR00CO31HZUKMS9RF673",
       "uri":
   "/dataTables/dataSources/cas~fs~cas-shared-default~fs~ModelStore/tables/_1LA3UXO
   R00CO31HZUKMS9RF673",
       "key": "FE93CC8BD5CEA0FBD1C2D4763785B9FC403DBB83",
       "caslib": "ModelStore",
       "location":
   "file:///models/astores/viya/_1LA3UXOR00CO31HZUKMS9RF673.astore",
       "host": "fall.edmt.sashq-d.openstack.sas.com",
       "fullPath":
   "/opt/sas/viya/config/data/modelsvr/astore/_1LA3UXOR00CO31HZUKMS9RF673.astore",
       "state": "success"
     }
   ]

To work around this issue, return to SAS Model Manager, manually clear the champion model flag, and reset that model as a champion model.
