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

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.

The same error:

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.

I created a new flow with only one action, i.e. the Copy File action.

and this gives the same error.

Also tried a different source file,

again same error.

Hi Sophia.

In SharePoint have site A with Home.aspx, that page hasn't been changed in a year. From then until yesterday, everything worked without a problem - we didn't change anything.
This site Home.aspx, when user request to create new site on Sharepoint form, then with power automate copy Home.aspx to new SharePoint site B. with option Replace.

Now i have done some tests manualy. Also try with option "Copy with a new name", but without success.

There is link to shared Photos ( upload there on page does not work to me ): https://photos.app.goo.gl/EbC2Ji3wgdJraLUR7

Error code is upper in first post.
Thank you.

Regards, Tadej.
