I set up SharePoint default value for the custom column by using SharePoint REST API with Power Automate. It set the default value; however, when upload a file to the document library, the default value does not show.

Here are the steps to reproduce the issue:

Create a new Modern team site collection not connected to M365 group by using PowerShell command ( New-PnPSite -Type TeamSiteWithoutMicrosoft365Group).
Create a new list in the new site and open list settings. Advanced settings -> Select Yes to Allow management of content types and OK.
At the settings page, select Add from existing site content types from Content Types.
Add a custom content type and select OK. This will add custom columns in the Columns section at the settings page.
Create a new document library and add custom columns which created at the step 4.
Set the default value for the column by using SharePoint REST API with Power Automate.
