Hi,
I am facing the same issue.
INFO: Page fetched successfully
INFO: 2 metatags were found
ERROR: No card found (Card error)
I have found the meta tags in the page source from the browser of that page. And this application is in my development environemnt and its url is http://localhost:8080/falabella-cl/product/3265845/NTB%20SA%20RF511-S08%20CI5%208G%201T%20W7P?skuId=3265845&passedNavAction=
html source under head tag
<meta name="twitter:card" content="product">
<meta name="twitter:title" content="Samsung Notebook RF511-S08 8GB">
<meta name="twitter:description" content="NTB SA RF511-S08 CI5 8G 1T W7P">
<meta name="twitter:image" content="http://<domainName>/is/image/<folderName>/3265845?$lista123$">
can Twitter cards be validated even from development environment?
can you please help me on this?
Thanks
Mohan
