CosmosDB with Mongo API failed to bind in Azure Function RRS feed

  • Question

  • Looks like you cannot bind output in Azure Function using CosmosDB with MongoDB API 

    For example, I am creating a Azure function with the Nodejs runtime.

    Here is the binding function.json

          "type": "cosmosDB",
          "direction": "out",
          "name": "outputDocument",
          "databaseName": "test-database",
          "collectionName": "test",
          "createIfNotExists": "true",

    In my azure function I'm adding a new entry into the collection(which is running Mongo API) with below code

    context.bindings.outputDocument = JSON.stringify({
        test: "test insert",

    However, function will failed with below exception
