formatMethodMap[type] is not a function in vision lib

[uliporeggia]

Just got this error calling vision.detectText

Debug: internal, implementation, error

I am using node v4.3.2 with hapi framework

[stephenplusplus]

Could you paste more of your code that triggers this?

[stephenplusplus]

I have a feeling it's an annotation error, possibly from a malformed image input type. We won't be able to know for sure unless you go into the node_modules/gcloud directory and edit the lib/vision/index.js file, adding a console.log(resp) around here: https://github.com/GoogleCloudPlatform/gcloud-node/blob/master/lib/vision/index.js#L349

I'll work on a PR asap that handles the type of situation I think you're running into.

[uliporeggia]

Yes, of course!
Here is the log:

{ responses: [ { error: [Object] } ] }
[ { error: 
     { code: 3,
       message: 'image-annotator::Malformed request.: Image processing error!' } } ]

That is it, something is malformed

[uliporeggia]

But this is strange because I am not making any manipulation on the image, I am just passing directly from hapi parser to vision API

    server.route({
        method : 'POST',
        path   : '/notas',
        config : {
            payload : {
                output   : 'file',
                parse    : true,
                allow    : 'multipart/form-data',
                uploads  : __dirname + '/uploads/',
                maxBytes : 1048576 * 10 //10 MB
            },
            handler : NotasRoutes.create
        }
    });

and then

var gcloud = require('gcloud');

gcloud = gcloud({
    projectId   : 'projeto-a',
    keyFilename : './credential.json'
});

module.exports.create = function (req, reply) {

    var vision = gcloud.vision();

    var data = req.payload;

    if (data.file) {
        vision.detectText(data.file.path, { verbose: true }, function (err, text, apiResponse) {

            if (err)
                throw err;

            reply({ text: text, apiResponse: apiResponse });

        });
    } else {
        reply({ erro : 'arquivo não encontrado' });
    }
}

I put together a PR that will make catching the error easier (#1334) (thanks for bringing this to our attention!)

As far as why the image is malformed, I can't be sure without testing the failing image and observing the steps that it goes through in your set up. Is it possible to put together a barebones repo so I can try locally?

[uliporeggia]

This is great! I thank you for answering my issue.
About the image, I think there is no needed more help, there must be some simple thing in my side.

Yar. I'm running into the same problem all of the sudden with cloudcats. Who knows which random reddit image is causing this. The problem is - I can't seem to find a way to work around the unhandled exception :(

Try out the PR (#1334) branch:

$ npm install --save stephenplusplus/gcloud-node#spp--1333

Where you were previously expecting results, say detections, there will be a detections.errors array. If all goes well, we can merge and release soon.
