BadRequest Status Code 400 – Failed to read parameters

Hey all,

Firstly, I'm very new to Flow so this may be something simple that I jus don't know?

I'm getting a BadRequest error 400 when copying a file to another folder in SharePoint with a date-time stamp as the filename.

Here's my flow:

flow-config.pngExpression: concat(formatDateTime(utcNow(),'yyyy-MM-dd, hh-mm'),'.','xlsm')


Here's the error:



Any help would be greatly appreciated 👍🏼

Hi @davehope ,


You couldn't name the copy file in your "Backup file" action.

We could only choose an option from the "If another file is already there" field in the Copy file action.



If you want to copy the file with a new name, you could take a try with the "Create file" action.

Hey, thanks for your reply.

I took a look at the "Create file" action but I have no idea how to tell it to use the existing file?

Basically, I'm looking for the SharePoint version of the ODfB action that works perfectly:


As you can see, it (simply) lets me select the existing file and copy it to a new location with a new file name.

Does anyone know how I can do that in SharePoint?
