REST call in workflow throws Error The parameter URL does not exist in method Add

Question

I have a workflow that created new sub-sites up until yesterday when it stopped working and started throwing the following error:

The parameter URL does not exist in method Add.

That parameter existed yesterday!

I haven't changed anything in the workflow as far as I know.

The workflow is using the /_api/web/webinfos/add to create a new sub-site.

Has anyone else encountered this error?

Are you passing URL property of Request Variable dynamically? Can you please check adding logs to workflow history if this parameter is blank in case of failed workflows? — Ganesh Sanap, Aug 13 '19 at 10:04

To troubleshoot the issue, you could republish the workflow.

And clear sharepoint designer cache.

And create a new same workflow to check if the same issue will occur.
