I'm guessing that the greater than and less than symbols are invalid, but maybe you just altered that to hide personal data.

I see you used the Body of the first HTTP request in the type field value of the second request. It probably is confused about that because the first request returns all properties of a list item instead of just a single property value of the library/list itself.

If you want to get the type value of your list/library you can use the ListItemEntityTypeFullName. I have also shared a blog about how to retrieve this type value:

https://www.expiscornovus.com/2021/07/10/listitementitytypefullname-within-power-automate/

I would suggest to change the URI of the Send an HTTP request to SharePoint to get type action to be below:

_api/web/lists/GetByTitle('Documents')/?$select=ListItemEntityTypeFullName

In the Send an HTTP request to SharePoint to rename file action use the below json in the body field instead:

{"__metadata": {"type":"@{outputs('Send_an_HTTP_request_to_SharePoint_to_get_type')?['body']?['d']?['ListItemEntityTypeFullName']}"}, "FileLeafRef":"Risk Findings.xlsx"}

Hi Expiscornovus,

I have used the below body content and after that old error is gone and getting new error as below :

File is not opened anywhere , the flow will generate this file (so every run the file will be NEW only) and then renaming it by using HTTP action . You can see full flow in the post.
How to overcome this error ?

{'__metadata':
{'type':'SP.Data.Shared_x0020_DocumentsItem'},
'FileLeafRef':'<New filename>'
}

That is because earlier in the flow you were still interacting with the Excel file via the add a new row action, which will lock it/consider the file still in use.

You can handle this behaviour in several ways. In your case why don't you rename the file before you are adding the rows to the table? Or do you have a specific reason to rename it at the end?

Alternatively, have a look at this article from Matthew Devaney with 4 other approaches:

This flow will run every week to generate this file , so to avoid duplications i have added utcnow in the file name.

Now i sorted this issue by adding delay action before the rename .

works well :) Thanks you ..
