I'm attempting to dockerize my fng projects. When using fng with the latest mongodb, attempting to 'list' my models returns the error:

Invalid query

Failed to parse: { find: "leaders", filter: {}, projection: {}, skip: {}, limit: 60 }. 'skip' field must be numeric.

I tracked this down to an assertion in forms-angular.js:

if (value && value !== ''  ) {
     ///build querystring
}

If the skip parameter happens to be 0 (Boolean(0) == false), this assertion will fail, and no skip parameter will be added to the querystring. I modified the assertion and the error is gone:

if (value && value !== '' || typeof(value) == "number" ) {
     ///build querystring
}
