Spring API won't map JSON to object if there is file in the request












0















In kotlin, I have this API



@PostMapping("/templates/send")
open fun translateAndSend(
@RequestParam payload: TemplateTestData,
@RequestParam print: String,
@RequestParam files: List<MultipartFile>,
response: HttpServletResponse
) {


And this data class



data class TemplateTestData(
val path: String?,
val targets: MutableList<String>,
val payload: MutableMap<String, Any?> = mutableMapOf()
)


and I'm trying to send files and object in JSON and my current setup doesn't work. I'm sending header content-Type - multipart/form-data and this is the request.



enter image description here
Unfortunately, I don't have the server response at hand right now. Does anyone know, what to change so the files are sent and the object is parsed? The request can also be changed.
