Getting an "Invalid card type" error in validator - all meta tags appear to be correct

Hi Stephen!

Do you know what specifically worked, so others can try the same thing? (Or was it just re-trying?)

Thanks!

rchoi · 2013-10-16T06:09:58.000Z

It looks like this instance works. Please feel free to try again.

After some heroic investigation on our engineering side, we found what might be the cause.

It turns out, our fetcher does some canonization of URLS, transforming http://www.raptorsrepublic.com/2013/10/09/practice-recap-valanciunas-english-cumulative-talent-ross-laid-back/ into http://www.raptorsrepublic.com/2013/10/09/practice-recap-valanciunas-english-cumulative-talent-ross-laid-back (Note the missing trailing slash on the second one.)

When I type the above no-trailing-slash URL in a browser, I get an empty page. Hence, the “Invalid Card type”.

I also noticed that you’re hosting a WordPress site. When I look at other Wordpress sites, I see it handle the no-trailing-slash gracefully by redirecting to the trailing slash version. Here are some examples:

Paedophile Jimmy Savile boasted to police he brushed away his accusers 'like midges', it emerged today.

blog.charitywater.org

Blog | charity: water

Stories and updates from the charity: water team, partners, and supporters.

Again, all redirect to the same URL with a trailing slash.

I can ask the engineers to take a look, but I know that may take some time. So I wonder, do you happen to know why your WordPress site is different than other ones, and is there something different in the configuration we could change to have it gracefully redirect like other wordpress sites?

Know it’s maybe not the most helpful, but I want to get you up and running soon – know you’ve been patient.

Thanks a ton!

Awesome! That was it. Working perfectly now. Just submitted an approval request.

Great to hear, and sorry for the delay. Any pointers as to what was going on with the trailing /, so all of our other WordPress users who face the same problem can learn?

Thanks again for following up!

Could the people that had there issue resolved give some feedback on what resolved the issue. I am having similar problems and am curious to the solutions.

I just tried validating for my site but am getting Invalid card type. http://www.eatcookexplore.com

Is the validator not working again?

rchoi · 2014-02-07T17:53:37.000Z

Hi there. It may take a couple attempts, but it’ll show your card and a submit button.

BTW, you’ll need to change your twitter:creator tag to a real username:

I’m having no luck at all! Cannot validate my twitter card.
Can get a preview - this is the meta stuff…:

But when I try and validate it I just get the invalid card type. Have tried with backslash at the end and without.
Any ideas what I am doing wrong?

Hi Rosanna, our validator will fail if you use tags with empty values. If they are not going to be used, leave them out altogether.

And an image URL is required for the summary with large image card, so you will need to fill in your twitter:image:src tag for the card to render. Do not forget to keep in mind that this image should be at least 280px in width, at least 150px in height, and less than 1MB in size.

So I believe everything should work fine once your code looks something like this:

Hi Ryan/Jon,

I am receiving an “invalid car type” error, while i try to validate player card for a video page on my site.
In the preview, i see that it is displayed correctly.

What could be the problem?

Hi Dimitar, I cannot see any cards metadata markup (meta name=“twitter:…”) tags in your page source, so the page doesn’t validate for me. Did you think you’d added the tags?

FramesDirect · 2014-07-02T15:58:00.000Z

I have a similar problem where I get the “Invalid card type.” error.

I’m using Google Tag Manager to push the meta tags into my product pages.

For example on this page, http://www.framesdirect.com/framesfp/Ray-Ban_RX-tdsjod/r.html, developer tools or firebug show the correct meta data added. If this is a problem with the tag manager implementation, is there a way to do this via GTM?

Here is the resulting meta data via firebug:

Thank you for the assistance.

rchoi · 2014-07-03T07:12:26.000Z

Hi @FramesDirect,

When I view source of your page, I don’t see any meta tags, or twitter:card. Perhaps I’m missing something?

FramesDirect · 2014-07-03T11:36:59.000Z

Thanks, Ryan. Not sure why my post isn’t showing up currently.

I think I figured it out. I’m using Google Tag Manager to push those into my product pages but found somewhere that Twitter only reads the page HTML versus anything inserted via JS. So, I’ll have to push this during a code update.

Thanks for checking.

Hi guys!
I am using Google Tag Manager to inject Twitter Cards meta tags. And I think it’s normal my cards cannot be validate. Right? What do you suggest to do to fix? Note that I cannot edit content from backend…

andypiper · 2017-01-06T14:30:36.485Z

Unfortunately the cards crawler cannot execute any Javascript and requires that the tags sit in the header of the page. You may need to find an alternative solution.

alemarengo · 2017-01-06T14:56:28.986Z

If you view this page you can see that obviously Tag Manager acts externally and execute a script that writes twitter card’s meta tags within the /head/ tag of that page. So… why the validator can’t see them?

andypiper · 2017-01-06T15:15:39.192Z

I just loaded that page in a browser, and I don’t see the twitter:card markup. I also pulled the page via curl -A Twitterbot and also don’t see that markup. GTM appears to sit inside the body of the page, so the browser would need to execute that script. Twitterbot (our crawler) cannot run Javascript. I’m not sure how you would make this work.

alemarengo · 2017-01-06T15:34:30.847Z

I navigate within a private window and I can see as in the attached image. What’s wrong then?
Moreover, you probably saw JUST THE SECOND PART of the Tag Manager script within the /body/ tag. Implementation instructions now, or better since a few months, say to do that.
