Route param only fetching first letter

Question

Route param only fetching first letter

I have the following code. It lets me fetch an image, and specify optionally if a recache is needed. For example, /something.jpg/force. It could also be the ID of an image, for example /7GDF4G. As you can see, the force param is optional.

app.get('/:image/:force?*', function (req, res) {
    console.log("image req");
    // Create variable to hold force bool, default is false
    var force = false;
    // Check if force bool is present
    if (req.params.force === ('force' || 'true' || 'recache' || 're-cache')) {
        force = true;
    }
    // Pass req, res, image variable and force bool to process
    mod.request.process({
        req : req,
        res : res
    }, {
        type : 'image',
        id : req.params.image
    }, force);
});

When run, everything is passed onto mod.request.process() as expected. However, if I add the following to see what value is being returned for :image:

console.log(JSON.stringify(data));

This is what is logged:

{"type":"image","id":"k"}

The input URL was kMoI9Vn.jpg/force, so id should be kMoI9Vn.jpg. If I run it again with something.jpg, I get {"type":"image","id":"s"}.

Any ideas on why this might be happening?

Why not just remove the asterisk and use just /:image/:force??

This works for both examples:

var pathToRegexp = require('path-to-regexp');

var keys = [];
var exp = pathToRegexp('/:image/:force?', keys);
console.dir(exp.exec('/7GDF4G'));
console.dir(exp.exec('/something.jpg/force'));

// outputs:
// [ '/something.jpg/force',
//   'something.jpg',
//   'force',
//   index: 0,
//   input: '/something.jpg/force' ]
// [ '/7GDF4G', '7GDF4G', undefined, index: 0, input: '/7GDF4G' ]
