Create a document in Cosmos DB via Logic App and PartitionKey mismatch in document & header

问题

So I'm trying to create an Azure Logic App which will create a new record inside a Cosmos DB collection to store review results.

I've created a Cosmos DB database (called icecream) + collection (called reviews). The PartitionKey of the reviews collection is /flavorIdentifier.

In my Logic App I have a step which inserts a new document.

The code looks like this.

"Create_review": {
    "inputs": {
        "body": {
            "flavor": "@{body('JSON_parseren_2')?['flavor']}",
            "flavorIdentifier": "@{body('JSON_parseren')?['itemOrdered']}",
            "id": "@{guid()}",
            "review": "@{body('E-mail_met_opties_verzenden')?['SelectedOption']}"
        },
        "headers": {
            "x-ms-documentdb-raw-partitionkey": "@body('JSON_parseren')?['itemOrdered']"
        },
        "host": {
            "connection": {
                "name": "@parameters('$connections')['documentdb']['connectionId']"
            }
        },
        "method": "post",
        "path": "/dbs/@{encodeURIComponent('icecream')}/colls/@{encodeURIComponent('reviews')}/docs"
    },
    "runAfter": {
        "E-mail_met_opties_verzenden": [
            "Succeeded"
        ]
    },
    "type": "ApiConnection"
},

So, I'm posting the message to Cosmos DB

{
    "flavor": "My flavor",
    "flavorIdentifier": "3",
    "id": "4927042a-faa1-4e09-9c6d-d038ef659b25",
    "review": "Very satisfied"
}

As you can see, I also specified the partition key to the same value as flavorIdentifier. My guess is this should just work. But it doesn't

The error I'm receiving states

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

Which is strange, as both have the same value, also when checking the raw input and output. Is there anything I'm overlooking?

For completeness, the full input and output of this step.

The raw input of the failed step.

{
    "host": {
        "connection": {
            "name": "/subscriptions/3b3729b4-021a-48b5-a2eb-47be0c7e7f44/resourceGroups/developerday-workshop/providers/Microsoft.Web/connections/documentdb"
        }
    },
    "method": "post",
    "path": "/dbs/icecream/colls/reviews/docs",
    "headers": {
        "x-ms-documentdb-raw-partitionkey": "3"
    },
    "body": {
        "flavor": "My flavor",
        "flavorIdentifier": "3",
        "id": "4927042a-faa1-4e09-9c6d-d038ef659b25",
        "review": "Very satisfied"
    }
}

Any thoughts?

Please add double quotation marks "" around your partition key and it works fine for me.
