Creates the Site Using PnP, but Hero Webpart causes Image thumbnail issue.

Question

Hi,

Created site using PnP provisioning, using below link,

https://learn.microsoft.com/en-us/sharepoint/dev/declarative-customization/site-design-pnp-provisioning

but when we published the template page from based site, all the thumbnail images removed for Hero webpart, not getting applied.

images are present under the SiteAssets, still unable to find the reference.

on console, we are getting the error,

{SPURL}/_api/v2.1/sites/{URL},{Uid data}/lists/{Uid}/items/{UID}/driveItem/thumbnails/0/{UID}/content?preferNoRedirect=true&prefer=extendCacheMaxAge&clientType=modernWebPart

{"error":{"code":"itemNotFound","message":"Item not found"}}

Can you please help us to resolved the query.

Thanks
