as per the samples I added GSON for content negotiation

install(ContentNegotiation) {
        gson {
            setDateFormat(DateFormat.LONG)
            setPrettyPrinting()
        }
    }

I created an extension function to catch post requests to an endpoint

fun Route.phrase(db: Repository) {    //db param adheres to repository interface
    post(PHRASE_ENDPOINT) {
        // get request from call, then
        val request = call.receive<Request>()
        // add on db, then
        val phrase = db.add(EmojiPhrase(request.emoji, request.phrase))
        // respond to call, sending back emoji phrase that was added to repository
        println("post: ${phrase.phrase} ${phrase.emoji}}")
        call.respondText("post received", contentType = ContentType.Text.Plain)
    }
}

I made a post request using curl

curl -X POST -H "Content-Type: application/json" -d tmp/request2.json <http://localhost:8080/api/v1/phrase>

this is the json file I am POSTing

{
  "emoji": "1234",
  "phrase": "test"
}

I get a server error when I try this:

java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING at line 1 column 1 path $%

It looks like this error is coming from the

call.receive<Request>()

call What am I doing wrong?

what you should get from that endpoint?

but if I comment out the respond I still get that error

so as I said above I think its the >call.receive<Request>()

aldo, receiveParameters are from web, not sure if you're doing the same

which would explain the error since it is referencing that its expecting a

{

but is getting

"

I changed my curl request and now it works!

(case closed)

what was the change with

curl

?
