All thre required data like All the meta tags are correct, html page response is also ~150kb, twitterBot can access pages. But still not able to validate the URL. I am getting below “ERROR: Fetching the page failed because the response is too large.”

Affected URL - https:// alifuat (dot) alifstores (dot) com/test-twitter (dot) html

Troubleshooting steps attempted:
I have checked html page response size, image size, meta tags.

This is specifically a problem with the HTTP headers size for this site - it exceeds 8192 bytes which is larger than the crawler will accept. The content-security-policy-report-only field is nearly 8k in total.

Hi @andypiper
What should be the size of content-security-policy-report-only to validate the card?

Well:

it exceeds 8192 bytes which is larger than the crawler will accept

The HTTP headers in total would want to be less than 8192 bytes. There’s no specific limit on that header entry.
