Handle multipart/form-data with Serverless? -

how handle multipart/form-data serverless-framework? v.0.5.6

just tried this:

"requesttemplates": {         "multipart/form-data": {           "httpmethod": "$context.httpmethod",           "body": "$input.json('$')",           "queryparams": "$input.params().querystring",           "headerparams": "$input.params().header",           "headerparamnames": "$input.params().header.keyset()",           "contenttypevalue": "$input.params().header.get('content-type')"         },         "application/json": {           "httpmethod": "$context.httpmethod",           "body": "$input.json('$')",           "queryparams": "$input.params().querystring",           "headerparams": "$input.params().header",           "headerparamnames": "$input.params().header.keyset()",           "contenttypevalue": "$input.params().header.get('content-type')"         }       } 

action.js:

export function respond(event, cb) {      var form = new formidable.incomingform();     form.parse(event, function(err, fields, files) {         if (err == null) {             var response = {                 status: "true",                 data: fields,                 error: []             };             return cb(null, response);         } else {             console.log(err);             return cb(null, apierrors.errors(402, err['message'] + fields));         }     });    } 

but got error: errormessage = "cannot read property 'content-length' of undefined";

i've got working serverless emulating http.clientrequest , using form parser tool formidable.

i'm using lambda-proxy api gateway event configuration.

const stream      = require('stream').readable; const formidable  = require('formidable');  module.exports.upload = ( e, ctx, cb ) => {     let form = new formidable.incomingform();      let stream = new stream();     stream.push( e.body );     stream.push( null );      // note: you'll want tolowercase() @ least 'content-type' header key     stream.headers = e.headers;      form.parse( stream, (err, fields, files) => {         // work parsed form results here.     }); }
