Postman: Cannot Create Document with Azure MongoDB API

Question

When creating the document with Azure Cosmos DB: MongoDB API, I am facing the below issues which varies on parameters.

When creating collection UserProfile, I've created it with Partition Key username.

Request1: - Without Partition Key

Headers:

x-ms-documentdb-is-upsert: true

Body:

{"username": "test"}

Issue:

The partition key supplied in x-ms-partitionkey header has fewer components than defined in the the collection.

Request2: - With Partition Key

Headers:

x-ms-documentdb-is-upsert: true
x-ms-documentdb-partitionkey: ["username"]

Body:

{"username": "test"}

Issue:

One of the specified inputs is invalid

Request3: - With Partition Key & id specified in body

Headers:

x-ms-documentdb-is-upsert: true
x-ms-documentdb-partitionkey: ["username"]

Body:

{"id": "test", "username": "test"}

Issue:

PartitionKey extracted from document doesn't match the one specified in the header

In any case,

I am not able to create the document. What are the necessary parameters to create the document which has partition specified?

Two points:

If you're using the Mongo API, you should not use the REST API. While it's technically possible, it is not supported to use both together. 100% do not recommend.
partition key needs to be the partition key value, not the path itself, so it would be "test", not "username". It already knows that "username" is the path.
