I keep getting the following error when trying perform a NSBatchUpdateRequest.
*** Terminating app due to uncaught exception
'NSInternalInconsistencyException', reason: 'Unknown command type
<NSBatchUpdateRequest : entity = Person, properties = {
"(<NSAttributeDescription: 0x6000000ff980>), name title, isOptional 1, isTransient 0, entity (null), renamingIdentifier title, validation predicates (\n), warnings (\n), versionHashModifier (null)\n userInfo {\n}, attributeType 700 , attributeValueClassName NSString, defaultValue (null)" = "\"sometitle\"";
}, subentities = 1'
The error log shows "entity (null)", when it is correctly specified in the constructor.
I am running this is a test environment and wonder if NSBatchUpdateRequest supports NSPersistentStoreCoordinator with NSInMemoryStoreType. I cant find anything in the docs say its not supported.
Below is the code I am using. The entity and property parameters are correct and shouldn't be causing the issue.
-(BOOL) updatePersonNamesFrom:(NSString*)oldName newName:(NSString*)newName {
NSBatchUpdateRequest* updateRequest = [[NSBatchUpdateRequest alloc] initWithEntityName:@"Person"]; // The person model definitely exists
NSLog(@"entity name: %@", updateRequest.entityName); // This logs the correct entity name
// Adding or removing a predicate has no effect
// [updateRequest setPredicate:[NSPredicate predicateWithFormat:@"name = %@", oldName];
updateRequest.propertiesToUpdate = @{@"name" : newName}; // Name field definitely exists on Person
NSError* error = nil;
[m_context executeRequest:updateRequest error:&error];
// Also tried this
// [m_context.persistentStoreCoordinator executeRequest:updateRequest withContext:self error:&error];
return error != nil;
}
If anybody has any ideas I would love to hear it.
