I am trying to use an Azure Functions httpTrigger call to delete an item from my database.

import { CosmosClient,  } from '@azure/cosmos'

const httpTrigger: AzureFunction = async function (context: Context, req: HttpRequest): Promise<void> {
    const client = new CosmosClient(process.env.cosmosDB)
    const database = client.database('testDB');
    const container = database.container('workers');
    const item = container.item('28a31558-ff8c-40c3-a7e8-1e8904c5ff72', '/id')
    console.log(await item.delete())
}

I even tried to hardcode the values into the code (as you can see) but I will always get 404 not found error:

  • 1 The 2nd parameter (partition key) in your call to container.item() should be the value of your partition key, not the path to the partition key. – David Makogon Commented May 11, 2020 at 12:52
  • 1 holy cow, this is working - if you post it as an anwser, i will mark it "correct answer". Thanks a lot. – Woozar Commented May 11, 2020 at 12:55

Reset to default 10

When retrieving a document via container.item(), the two parameters are:

  • document id
  • partition key

The 2nd parameter (partition key) needs to be the value of the partition key. In your example, you had the path to the partition key instead, so it's checking for a partition key value of "/id":

const item = container.item('28a31558-ff8c-40c3-a7e8-1e8904c5ff72', '/id')

This needs to be changed to:

const item = container.item('28a31558-ff8c-40c3-a7e8-1e8904c5ff72', '<partition-key-value')
