Unable to preview store page in dev portal

Unable to preview store page in dev portal. Get the following error when trying to preview changes in both dev and stage.

Echoing what I mentioned in your DM to me for others to see, in case they’re running into the same issue:

This looks to be an unintended byproduct of a recent change that was rolled out, which I’ve made the team aware of. In the meantime, you should be able to work around this by setting the “Early store discovery” date to sometime in the past, saving that change, and then attempting the preview again shortly later. Once you’ve successfully done the preview and things are to your liking, you can revert the “Early store discovery” date back to what you had it, save again, and you should be good to go.

Update: We rolled out a bug fix earlier this morning that aims to address this issue, so hopefully all is well once more. But please do let me know if you continue to see any oddities and we will of course investigate further.

Thanks for your patience with this!
