How can I see the json generated from Ktor?-CodePudding

I want to see the json result of the body but I have no idea how, I am recieving a 400 bad request and I am pretty sure the issue comes from "listOf(PostInvoiceResultInsideLineItems("API", 1, furiousInvoice.amount_inc_tax, "1", "FR_200"))"

In the API, it needs something like this:

"line_items": [
               {
                    "label": "API",
                    "quantity": 1,
                    "currency_amount": 2000,
                    "unit": "1",
                    "vat_rate": "FR_200"
               }
          ],

And the only way I could think of including the [] in the json was with listOf but I am not even sure it is writing it correctly hence the need to see exactly what Ktor is sending in Json.

suspend fun postInvoiceImport(furiousInvoice: GetInvoiceData, pennylaneId: String, vat: String, pdf_base64: String): Result<PostInvoiceResultResponse>{
    return client.post("${apiName}/import") {
        contentType(ContentType.Application.Json)
        setBody(
            PostInvoiceResult(
                PostInvoiceResultInside(
                    PostInvoiceResultInsideCustomer(pennylaneId),
                    listOf(PostInvoiceResultInsideLineItems("API", 1, furiousInvoice.amount_inc_tax, "1", "FR_200")),
                    furiousInvoice.invoice_date,
                    furiousInvoice.due_date,
                    "F"   furiousInvoice.id
                ),
                "false",
                pdf_base64
            )
        )
    }.toResource()

I tried to use Postman and even made all the necessary steps to capture HTTPS request but it doesn't detect Ktor requests.

You can install the Logging plugin with the LogLevel.BODY level to observe a serialized request body. Here is an example:

val client = HttpClient(Apache) {
    install(ContentNegotiation) {
        json()
    }
    install(Logging) {
        level = LogLevel.BODY
    }
}

client.post("https://httpbin.org/post") {
    contentType(ContentType.Application.Json)
    setBody(listOf(123, 434, 777))
}

Here is an example log:

2022-07-13 09:01:19.127 [main]  INFO  io.ktor.client.HttpClient {} REQUEST: https://httpbin.org/post
METHOD: HttpMethod(value=POST)
BODY Content-Type: application/json
BODY START
[123,434,777]
BODY END
