schema: type 'string' and format 'file' throws error

[kane-mason]

I wanted to make use of the file choose button as detailed here https://github.com/thomas4019/expressa/blob/master/doc/uploading-files.md

"profile_photo": {
    "type": "string",
    "format": "file",
    "links": [
{

But in the admin panel it causes an error in the console if the property already has a value

Mmm if i make media.binaryEncoding = 'base64' the error goes away but still doesn't show the value

might be an incompatibility, because i accept the data as a b64 string and then write to disc and persist the url and not b64 data
