Power Automate Copy file no longer works - Copy SharePoint Home.aspx to New SharePoint site

Experiencing the same as Bart and Tadej and this flow and sharepoint file were created last week. Everything was working just fine but now getting the same error. Tried creating a new flow but no luck with that. Same error.

Invalid number value.

The same error:

Same here. Something seems to have changed after Sept 18 05:24PM - this was the last successful run of a flow which uses the Copy File action for a page. All runs in several flows which copy pages between sites have failed since then with the same error.

I've done a lot SharePoint server-side development in the good old days and for me it seems that, there was a change in SharePoint (update of schema files or code) which causes the interal SSOM API call to fail when it "hits" the actual schema.

The thing is: Opening a standard ticket for this as a customer is pure pain when explaining this to the 1st level support. Let's hope that the issue causes some important flows in large orgs to stop, so premium support gets fired up.

I'm also having this exact error. The automation was working perfectly fine yesterday and nothing had changed, but as of about 10 hours ago all of a sudden its broken and I'm getting the following:

Same error with my flow that has been working fine for years before today.
