Upload a file to an S3 using a presigned URL

[hnxtay]

Ktorfit version

1.12.0

What happened and how can we reproduce this issue?

I want to use a presigned URL to upload a file to S3. However, I am facing an error even though I have provided the URL and the request body.

Exception in thread "worker-1" java.lang.IllegalStateException: Fail to prepare request body for sending. 
The body type is: class okhttp3.RequestBody$Companion$asRequestBody$1 (Kotlin reflection is not available), with Content-Type: null.

If you expect serialized body, please check that you have installed the corresponding plugin(like `ContentNegotiation`) and set `Content-Type` header.

this is my code:

@PUT
    suspend fun uploadImageToPresignedUrl(@Url url: String, @Body requestBody: RequestBody)

I attempted to include 'Content-Type: multipart/form-data' but it resulted in an error.
