Update Profile Image "Request Header Fields Too Large"

[michellebergero]

Is there a way to upload a new profile image using the REST API (/1.1/account/update_profile_image.json)? Using axios with node.js, I’m finding that if I use a base64 encoded image as a query param, I get a 431 error “Request Header Fields Too Large”.

Here’s the actual response (with oauth stuff removed and image string shortened):

[debug] err.response {
