I'm trying to upload a file to REST endpoint in Spring, but it always says:
Possibly unhandled rejection: OPTIONS 401: unauthorized, and then the parameters of the operation.
This endpoint service is a POST one, and it looks like UPLOAD is trying the OPTIONS method.
The endpoint says that 3 authentication parameters, are not present, even though they are.

Any ideas? Thanks.
