Deleting all items from cosmos DB in batch: 404 not found

Question

I have following code:

CosmosClientOptions options = new CosmosClientOptions() { AllowBulkExecution = true };
CosmosClient cosmosclient = new CosmosClient(connStr, options);
Container container = cosmosclient.GetContainer("CoachAPI", "Vessels");

await VesselsContainer.DeleteItemAsync<CoachVessel>("81c91c3a4f4841529bf36badfbb4a2ba", new PartitionKey("name"));   
or
await VesselsContainer.DeleteItemAsync<CoachVessel>("81c91c3a4f4841529bf36badfbb4a2ba", new PartitionKey("XXXa Soya"));

When running code I get:

code does not indicate success: NotFound (404); Substatus: 0; ActivityId: ; Reason: ();'

Any pointers how to fix this?

Partion key: /name

Answer 1

Make sure, that you use the correct container. In your case

Container container = cosmosclient.GetContainer("CoachAPI", "Vessels");    
await container.DeleteItemAsync<CoachVessel>("81c91c3a4f4841529bf36badfbb4a2ba", new PartitionKey("XXXa Soya"));

instead of

Container container = cosmosclient.GetContainer("CoachAPI", "Vessels");
await VesselsContainer.DeleteItemAsync<CoachVessel>("81c91c3a4f4841529bf36badfbb4a2ba", new PartitionKey("XXXa Soya"));

The code has been tested in person and you can copy it directly to your project and run it.

The format of item is shown in the figure.
