i don't know origin of error, on config.yml doctrine mapping set auto

thank in advance help

edit 1

i have refactored code scenario :

the upload request independant, has own isolated request content-type set multipart/form-data

this time not have problem, but..the same error still here :

{   code: 500   message: "the class 'symfony\component\httpfoundation\file\uploadedfile' not found in chain configured namespaces sowq\bundle\userbundle\entity" } 

i wondering if that's not bug or compatibility issue between symfony 2.7 , doctrine uploadable extension, idea?

i think problem or (uploadablemanager extension - don't know this) try set object file (of type "uploadedfile class")

$avatar file object if want save database, need datatype blob. usually, before save file on file system , save $avatar on db, $avatar file path or file name o link file system resource
