I have a multipart upload API that works flawlessly when I upload a file via Postman. However, when I upload via the same API but using Fetch API, I get 413 error.
I tried the solution given here but it did not work.
My JS code is as follows -
async function uploadAudio(formElements) {
const formData = new FormData();
const file = fileUploadField.files[0];
formData.append("file", file);
console.log("Name: " + file.name); // Prints the correct file name
console.log("Size: " + file.size); // Prints the correct size (which is < than what is set server side)
const options = {
method: 'POST',
body: formData,
headers: {
'Content-Type': 'multipart/form-data',
'Accept': 'application/json',
'Authorization': 'Bearer ' + authTokenArr[0]
}
};
const response = await fetch(base_url + "/audio/file", options);
const data = await response.json();
if (response.ok) {
handleSuccess(data);
} else {
handleFail(data);
}
}
application.properties file -
# max file size
spring.servlet.multipart.max-file-size=10MB
# max request size
spring.servlet.multipart.max-request-size=10MB
REST controller -
@PostMapping("file", produces = [ProduceTypes.JSON])
fun uploadAudio(@RequestParam("file") file: MultipartFile,
@RequestHeader (name="Authorization") token: String): ResponseEntity<MutableMap<String, Any>> {
val user: User = userService.getUserDetailsByToken(token)
val body: MutableMap<String, Any> = LinkedHashMap()
body["status"] = ApiStatus.UPLOADED
body["fileId"] = podcastFileService.uploadFileToB2(user, file)
return ResponseEntity(body, HttpStatus.CREATED)
}
Here is my server side log -

Why would there be a size problem when the API is working fine via Postman and even when uploaded using mustache template with a non-REST controller.
