Invalid request after trying to update ContentType column

Workflow Actions Pack Microsoft 365 version
1

I’m trying to update the Content Type of an item from Folder to Document Set using the Update List Item at Any Site action.
First, I create a dictonary with these values:


Then, get the action configured:


The workflow gets terminated, logging “Exception: Solicitação inválida.”, witch translates to “Invalid Request”.

Without changing the ContentType colunm, altering the propertie “HTML_x0020_File_x0020_Type” to “Sharepoint.DocumentSet” results in a URL error, clicking the folder doesn’t open the page correctly.
