Issuer API parser error: "SyntaxError: Unexpected token D ..."

[nfreear]

Hi,

I'm not sure if this is a bug on our side or in the Issuer API...

When we try to add badges from a site I maintain called Cloudworks to Mozilla Backpack we're seeing errors.

This seems to be the relevant part of the error:

"message":"Unexpected token D","stack":"SyntaxError: Unexpected token D\n at Object.parse (native)\n at Request._callback (/var/www/openbadges/node_modules/openbadges-validator/lib/resources.js:111:21

• HTML page, http://cloudworks.ac.uk/badge/issue/364
• Assertion, http://cloudworks.ac.uk/badge/assertion/364
• https://backpack.openbadges.org/issuer/assertion?assertion=http%3A%2F%2Fcloudworks.ac.uk%2Fbadge%2Fassertion%2F364
• Badge, http://cloudworks.ac.uk/badge/badge_class/8.json
• Organization, http://cloudworks.ac.uk/badge/organization.json

The assertion validates:

• http://validator.openbadges.org/?assertion=http://cloudworks.ac.uk/badge/assertion/364

I've experimented with shortening the description for the Badge-Class, to 128 then to 64 characters.

Can anyone spot the problem please?

Many thanks,

Nick

Hi Nick,

Try getting rid of the backslashes in the url values.

Hi kayaelle,

Thanks for the swift response!

Yes, I see why this might be a problem. The "/" is valid JSON I think, but JSON Lint replaces them with "/" in the pretty-printed output. And there is now a constant in PHP,

FYI, I've fixed here,

Thanks again, Nick.
