Custom pages occasionally get provisioned as corrupted (`NoComponentId` error)

[JakeStanger]

Occasionally when provisioning out a page, the resultant page is corrupted. This crashes the provisioning process. Attempting to re-apply the template crashes at the same point with a null reference exception:

Object reference not set to an instance of an object.

Attempting to open the page shows a "Something went wrong" error page citing NoComponentId with no further information.

This has happened maybe 150 times out of around 15,500. Deleting a site with the corrupted page and reprovisioning it has always resolved it. Both of these point to it looking like a race condition maybe?

We always apply the template to freshly created team sites using the out of the box team site template, so the sites have had no visitors or customizations to interfere with anything.

The below is a shortned version of the template we're using, containing only the full page that gets corrupted (minus the custom web part properties). The page contains four web parts:

• 1x OOTB text
• 2x custom web part
• 1x another custom web part
