loadMatView afterLoadScript error when calling a function

I'm using Teiid 9.0.0

Here is the afterloadscript:
"teiid_rel:MATVIEW_AFTER_LOAD_SCRIPT" 'execute implify_dataModel.native(''ALTER TABLE "implify_data"."User" RENAME TO "implify_data"."User_temp"'');execute implify_dataModel.native(''ALTER TABLE "implify_data"."User_stage" RENAME TO "implify_data"."User"'');execute implify_dataModel.native(''ALTER TABLE "implify_data"."User_temp" RENAME TO "implify_data"."User_stage"'');execute implify_dataModel.native(''truncate table "implify_data"."User_stage"''); SELECT ON_VIEW_LOADED_COMPLETE(''VIEW.B7F553FA-4F52-45FE-82BD-E2C18A4658B2.User'') '

the call of the following function is causing the exception, but i did not find the log file where the exception is written
SELECT ON_VIEW_LOADED_COMPLETE(''VIEW.B7F553FA-4F52-45FE-82BD-E2C18A4658B2.User'')

if I put the function into ON_VDB_DROP_SCRIPT, it is called successfully
