Is possible send empty array by FormData?

[wildfrontend]

i use Automatic serialization to FormData to send empty array

but it look like ignore empty value

is automatic object serialization to a FormData object can send empty array?

An empty array can't be represented in FormData as this is a flat data structure that only emulates data nesting, but you can send JSON string as a field value.

await axios.postForm("http://localhost/", {
  emptyArr: JSON.stringify([])
});

Unfortunately, at the moment server frameworks (like multer) do not support automatic deserialization as there is no established practice of serializing JSON into FormData fields, so you need to do it manually
