Buffer.write(string, encoding, offset[, length]) is no longer supported (Node.js 6.x)

[integritybit]

Hello,

Awesome library. Thank you . We are building a proof of concept using your wcf.js and Node 6.x. Getting an error in buffer.js with message "no longer supported"

Here's the error:
`
node app.js
Hello world
buffer.js:735
throw new Error('Buffer.write(string, encoding, offset[, length]) ' +
^

Any ideas?

Thank you.

@integritybit I just ran into this error also wondering if you ever found a solution?

[chrisgh1]

Found the solution. it is a problem in the node module formidable in the file multipart_parser.js on lines 61 and 62. You need to change them to this
this.boundary.write('\r\n--', 0, 'ascii'); this.boundary.write(str, 4, 'ascii');

just switch the 2nd and 3rd arguments.

[chrisgh1]

After further investigation it looks like the bug in formidable was fixed in recent versions. I installed formidable version 1.1.1 and removed formidable version 1.0.9 and everything seems to work. I noticed in the package.json that the dev specifically calls for formidable version 1.0.9 ie( "dependencies": {
"bufferjs": ">= 1.0.2",
"dateformat": ">=1.0.2-1.2.3",
"formidable": "=1.0.9")

I don't know if there is any ramifications of using a more updated version of formidable but maybe the dev can chime in.

Thank you @chrisgh1 sorry this is an old comment I know, but it just worked for me.
