Logs or notes

SmartFrame guide to embed on WordPress, it recommends using an HTML block to add the script to embed. https://smartframe.io/support/embed-smartframe-on-wordpress/

SmartFrame block was previously fixed in https://github.com/Automattic/jetpack/issues/21062.

Context: ran into this while updating some docs and testing the Jetpack blocks.

Interestingly, it seems to work at times, but the connection randomly fails, sometimes with this CORS error:

The Same Origin Policy disallows reading the remote resource at https://static.smartframe.io/themes/null/default.json. (Reason: CORS request did not succeed). Status code: (null).

@Automattic/apex Did you happen to have contacts at SmartFrame back when you worked on this embed implementation? It may be interesting to have someone on their team take a look at this, to ensure that oEmbeds still work well on their platform.

Thank you!

This issue has been marked as stale. This happened because:

• It has been inactive for the past 6 months.
• It hasn’t been labeled `[Pri] BLOCKER`, `[Pri] High`, `[Type] Feature Request`, `[Type] Enhancement`, `[Type] Janitorial`, `Good For Community`, `[Type] Good First Bug`, etc.

No further action is needed. But it's worth checking if this ticket has clear reproduction steps and it is still reproducible. Feel free to close this issue if you think it's not valid anymore — if you do, please add a brief explanation.

Hey Jeremy 👋🏼 Thank you for the ping. This one must have fallen through cracks. Sorry about that. 😬

Did you happen to have contacts at SmartFrame back when you worked on this embed implementation?

AFAIK, we don't have any contacts at SmartFrame.

Just noting that the issue is still reproducible by following the steps in the issue description.

I have added the task to the Build maintenance board so it can be investigated further, however, I am afraid that in Apex we won't have enough bandwidth to look into this issue in the near future.
